The morning was fantastic, amazing weather, great company, getting into the great indoors, but all of this was abruptly forgotten as we got out of the car in Pontsticill and got to the hill we had to climb. There’s no easy way to Trefil, other than a long flat walk from Trefil village, but it takes us about double the time to walk from there, so we go straight up the mountain.


We had two objectives for the day, get Chris past the first boulder choke, and get some footage for a video.
We got kitted up at the cave entrance, for the first time we heard debris coming off of the cliff above the entrance, so stayed very cautious around the face.
The trip went really well, and we got some great footage of the cave. Chris got through the first boulder choke, and managed to make it part way through the “second choke” before becoming exhausted, and soon after Peter had reached his limit. Gareth and I pushed a little further, reaching the tight end series, but soon after stopped to save the others getting cold hanging around.


Back on the surface we made our way back out of the main quarry, had some lunch, and headed around towards Cwar Yr Hendre – Quarry cave 8. We have visited this cave before, but pushed for time, we had to leave. We spotted some red and white tape in there previously, so wanted to see what it was protecting. Unfortunately Gareth and I think a thin layer of roof may have peeled off and covered whatever was there. With everything looking very unstable we headed back out.
Last on the list is a cave which isn’t registered, as far as I could see, but I suspect it’ll fall into the Cwar Yr Hendre – sites 1-8, or 9+ if newer than the others, because it’s definitely been dug to join with another cave. High on the north face is where you come out, after entering through the opposite face to Cwar Yr Hendre – Quarry cave 8. Both caves were small, but still enjoyable.
After being cooked in my caving gear, or so it felt like anyway, I was happy to get it off and chill out in the last of the sunshine.

Will’s Hole 27th July 2022

Will’s hole is a relatively small cave with not an awful lot to see in the way of formations, but what it does have is a very simple pitch. Gareth and I have been learning basic SRT for a few months now, and have been keen to try it out underground. We know it’s a very busy spot along that river, so we had two mates, James and Steve come along and make sure nobody tampered with our ropes.
We all met at Gareth’s house for 5:30pm, and made our way to Dinas Rock. Gareth and I kitted up, and we all headed up river to wills hole. There were loads of people out climbing and bouldering, and a few interested in what we were up to.
It was about 7pm by the time we arrived at the cave entrance, and we didn’t hang around, straight in, down the 2m free climb and at the first rigging point, a railway track across the rift passage. Rigging was straightforward, I used my hand jammer as a lanyard to rig at the pitch head, and it worked well.
Once ready we wasted no time, I couldn’t, I’m way to nervous with heights, so I loaded up my descender, and sat into my harness, I was really nervous, but confident in mine, and Gareth’s ability, and I started the descent of our first SRT trip. We were both soon at the bottom without a hitch. We got our SRT kit of and headed to the right side passage. There isn’t much in the way of formations on this section, but there’s plenty of mud! Thick, silty, sticky, glutinous, mud that you have to crawl through. We came to a choke and couldn’t see a way on, so headed back to the pitch to look at the other passages. The main passage is nicely decorated at the high levels, along with a lot of flood debris, giving a good idea how high the water gets in there.
Before long we were at the end again and headed back out. Gareth went first, and both ascending without a problem, and de-rigging going just as well.
In what felt like no time at all, but it was actually about 2 hours, we were back on the surface with James and Steve chatting to some climbers.

Agen Allwedd The Grand Circle – 22nd May 2022

Dai MacDonald

Louise Lucas

I arrived at Whitewalls first, then had the message I’d been waiting for, Gareth and Louise would be late, so I made a coffee, rolled a cigarette, and walked across the tram road a little and sat in the sun.

As I walked back to Whitewalls I could see Louise getting out of the car. We got kitted up, sent the call out, and made our way across to Aggy. Louise was excited to get into Aggy again, the last time she was in was on a newbies trip before joining the club.

We made steady progress through the entrance to Baron’s Chamber, but as usual we were all sweating by the time we got into Baron’s Chamber. After a quick drink stop we were off, and heading for Main Stream. Louise had a slip on the hand-lined section in Keyhole Chamber, but got herself back up and across fine. A little longer than I remember we were at North West Junction, we were all on guard as this section is really slippery. There definitely seems to be a theme emerging, Louise falls into water. We made speedy progress towards Deep Water, which is Gareth’s and my furthest point from the last trip we did here. Without hesitation I waded in getting to waist deep, as described in journals and online, and then Gareth asked “is it getting any deeper”, and as I was replying “I don’t think so” I slipped down to shoulder depth and started struggling to catch my breath, so I headed back still trying to catch my breath. We had a quick talk about the best way to approach it, then Louise opted for swimming so far and trying to stand, and she couldn’t reach the bottom after swimming out a short distance, so turned around and I helped her back to shallower water. We talked a little more, but being completely unsure of how long we’d be swimming for, and how we’d feel swimming fully kitted up, we all agreed the best thing to do was head back the way we came. Just before heading back Louise stayed true to form and had a dunk again, while trying to help her, Gareth had a soaking as well. Heading back was fine, apart from us all being a bit miserable after another failed trip here, because of this we just headed straight out.

As I got out of the cave there was a guy asking, do I knew if the small phreatic tube outside connects into Aggy, I said it didn’t as far as I know, and asked “why’s that” he said his dog has gone into it, as I walked over to him, Louise and Gareth got out. We tried looking in with our lights, whistling, calling, and putting food down, but there was no sound at all. He said he’d called Cave Rescue, so they were on their way. We said we’d head back and ask some advice about it and maybe see if anybody else can head over to help. Once at Whitewalls the police and cave rescue arrived, so we left them to do their work, and we headed home. Once home we heard the news that the dog was safe and with his owner again.

We started the day joking about Gareth’s forgetfulness, and it definitely set the tone for the day! As we’re pulling off the A465 at Brynmawr, to collect the key from Barry, Gareth says “I think I’ve forgotten my helmet”, which also means his torch as well. We collected the key, and then heading back to Merthyr Tydfil to collect Gareth’s helmet, we were on our way again, with Gareth reassuring us “I’ve got my batteries, because I charged them last night” he didn’t have his batteries, he’d forgotten them as well, but I’ve got spares so it was fine. After changing we like a cuppa and cigarette before getting going, Gareth had also forgotten his tobacco!

We quickly headed for the entrance as we were all starting to get quite hot in our caving gear. This was Peter’s first trip into a gated system and instantly he was shocked with how tight the entrance was. We made great progress through the entrance as we talked Peter through certain sections, and finally helped show the technique needed for the entrance pitch. Before we knew it we’d signed the log book at 12:30, and Gareth and I were trying to convince Peter he should try Beer Challenge, on his own, and we’ll meet him in White Arch Passage, he declined our challenge! We made it to Indiana Highway in a good time, and got straight into it after a drink stop. As we got to the end of the traverse, someone said they’d forgotten their phone and snacks at the start of the traverse….so Gareth headed back to the start of the traverse line to retrieve his stuff, fortunately this was the last time he forgot something….that day! We made our way to the junction for Megadrive and Megadrive North, and headed to Megadrive North, and then back down Canyon North to the guano pile at the start of Canyon West. After this we headed for Siambre Ddu passage, where we were all coming up with different pronunciations for Siambre. We got back to Megadrive and continued towards the Nunnery, where we detoured to Arms Park through Perseverance II, just to show Peter the way on to the other parts of the cave. Once done we headed back out in good time, and in time to enjoy the sun while changing. Overall it was a great trip, especially for Peter, who is keen to find out more about becoming a club member.

We all arrived at SWCC cottages for around 10am, and couldn’t believe how busy it was, there’d been an AGM meeting the day before, and it was the bank holiday weekend.

Key acquired and we headed for the entrance, a tall opening with a short ladder climb down to the gate, which was opened as there were a few guys going in to do some scaffold work, so I volunteered to carry a few short lengths down for them.

Soon we were in, and off with Gareth leading the way. We passed the concrete walkways fairly quickly and got into some lovely passages before dropping into the Main Streamway. A lot quicker than we all expected, we were passing the 1st pot, 2nd pot, and Maypole Chain. The streamway is really something special, with the white veins running through the black rock. We passed 3rd pot, 4th pot, and the sump, and carried on along the streamway for quite some time. Eventually we were through Boulder Chamber and out of the Main Streamway, we found ourselves scratching our heads and looking at the survey, following the description we’d gone too far and ended up in OFD 1 1/2, so doubled back to get on route again. After a few more survey stops we were back at the fixed rope and ladder to get into Lowes Passage, which has a huge boulder slope to climb, but not before Louise had a proper dunking in the Main Streamway. Then we were soon into Roundabout Chamber, this whole section of cave is stunning, all the way through to Rawl Series, and Pi chamber. Helter Skelter and Bolt Passage were fun, basically like a big slide, with vertical bits though! Soon we were traversing across Bolt Traverse and Maypole Wire, which definitely got my heart thumping, even with my cowstails clipped on. Before heading across Maypole Wire, Gareth suggested heading the other way, towards Rocky Holes Chamber, and in hindsight I should’ve turned around, but I was committed to the wire route, and we headed down Maypole Chain into the Main Streamway for Louise to have a good dunking again. The rest of the way out was great, and without fault. At the ladder to climb out I found a frog, so took it outside with me, and we posed for a few photos before heading back to the cars after another great trip!

Aggy, Inner Circle 17th April 2022

Aggy, Inner Circle 17/4/2022 by Dai MacDonald

Maxine

Gareth and I arrived at Whitewalls with a stubborn white fluffy dog laying in the middle of the road, even after Gareth got out to coax it out of the way, it just walked along the middle of the road. We parked up, eventually, and got changed, sent the call out message and were ready to leave when Tom and Maxine pulled up outside Whitewalls. We were both planning an Inner Circle trip, so decided to head in together. Tom and Maxine got ready quickly and we were on our way across the tram road.
Once in the cave we made quick progress through the entrance series into Baron’s Chamber, where we stopped momentarily to catch our breath and have a quick drink. In no time at all we were at the Second Choke, and into Keyhole Chamber. We each had turns in leading and all managed well, although I’m sure I suggested a wrong turn or two, but we were soon at North West Junction. From here we headed for Turkey Pool, but on the way through Turkey Streamway Maxine said she’d like to call it a day, she had been caving the day before and felt really tired. We parted ways, with Tom and Maxine saying they’d have a look at Beehive Chamber before they left, and Gareth and I heading for the Inner Circle. Soon we found ourselves at Turkey Pool, I managed to traverse it, only getting my legs wet, Gareth traversed it as well but got a bit wetter. The rest of the way was no problem, and soon we were at the rescue dump around the Inner Circle. We stopped here for a snack and a drink, then made our way around the inner circle clockwise…so we thought! Before we knew it we were in the Swiss Village, this threw us completely, and we both started looking at the survey and scratching our heads. We retraced our steps and made a few more wrong turns, then decided we would call it a day and start heading back out. For the best part we were okay, but we made a few wrong turns on the way out as well, mainly me I think, but soon we were in the entrance series, and then at the logbook. We checked for Tom and Maxine, they were both ticked out, so we signed ourselves out for 1805, and headed back to whitewalls to get changed just in time before the rain started. Overall a great trip, and worn out for a trip to OCAF the following day.

Dinas Silica Mines and Local Caves 10th April 2022

We wanted an easy day, so thought we’d check out the mines and wills hole, to the pitch head anyway. We met for 10am and got ready, and headed off after a cuppa. The mines were really interesting, but nothing compared to a cave, strange! We all commented on the steepness of them, then found ourselves in a shaft that went straight from the bottom to the surface, so we stopped for a snack and made our way onto the other mines. While walking the river we were stopping, looking at other bits of interest, and finding violets and wild garlic, but aiming to find Will’s Hole. Soon we found ourselves past both bouldering areas, and down past the lower caves, Ogof Bwa Maen Lower Cave, so doubled back and found Will’s Hole, which we all found disappointing because we could only go a few meters down into it. Ogof Bwa Maen caves on the other hand were quite an interesting, once I’d got past the spiders. We finished off looking down the rest of the river until we got to Ogof Pont Sychryd which we all enjoyed, but my highlight was finding a Morel Mushroom at the entrance, I’ve been looking for a while. After this we headed back to the cars, got changed and headed to the top of the Dinas Rock to enjoy the sun.

We started our day full of beans ready for the round trip, and had decided we’d try some alternative routes to the usual ones.

We got in for around 11:05 and made steady progress through the entrance while getting good footage. We made it to Cairn Junction and headed for a bad decision, Beer Challenge! We just wanted to see for ourselves what it’s like, and I’m happy to take Wonderbra any other time now. After this the trip went great all the way through Lamb and Fox Chamber, Indiana Highway, Megadrive to St David’s hall, then the survey came out for Squirrel Rifts. This was another route we wanted to try, rather than Agent Blorenge II. Once at the two climbs, at the end of Squirrel Rifts, we got a little confused where the way on was, but soon found the climbs and made our way down them. The squeeze to get into Haggis Basher is surprisingly demanding and I struggled with my bag and bottle through there. We had a look along the passage, to the choke and then back on ourselves to head for far Agent Blorenge and Chocolate Blorenge, by this point the both of us were feeling quite fatigued after the crawling. We carried on towards the sewers, thinking we’d done the hardest bits, but soon found ourselves at a hole dropping down in a rift that I tried to pass through but felt it was too tight, we looked for an “eyehole” that’s shown on the map, but not even knowing what an eyehole is, and both being on our last battery, we decided to head back the way we’d come. Instantly I was filled with dread just thinking of the two climbs we faced to get out of Haggis Basher, as I’m not the most confident with heights. When we got to the squeeze out of Haggis Basher, we searched the survey for an alternative route to no avail, so pushed through to the climbs. I went first, both no problems with the first, but on the second the exposure got to me, and when I climbed it the first time I didn’t go high enough to climb out and convinced myself I couldn’t do it, but spotted a climb in the opposite end of the small rift, which I could then traverse across the top. I climbed up confidently and found myself on a small solid ledge so stopped to look where to go, panic set in rapidly and I felt extremely exposed, so I climbed to the top of the passage where there was a small dead end tube I could sit in. I shouted down to Gareth “I’m stuck, I can’t down climb from here and I can’t make that traverse”, he could see nothing from the bottom, so he decided to try the climb where I tried first. He climbed up, passed the opening confidently and easily into squirrel rifts, while I’d quietly been having a panic attack, thinking to myself “what’ve you done Dai, you idiot! This is cave rescue now”. Gareth started suggesting things while I told him “I’m stuck bro, I can’t go anywhere”, then I’m the next breath, “just let me calm down and I’ll get across the traverse now”, and continually switching between the two for about two minutes. I asked Gareth to turn his light down because it was blinding me, and by the time he looked back I was across the traverse. Once I’d calmed myself the traverse out was actually really easy. From here we headed for Agent Blorenge II to save on time as we were running out of it. The rest of the trip went fine and we were out before we knew it, making the long walk back to the car.

Ogof Draenen – Sunday 20th March 2022

We met up on the not so bleak Pwll-du, the sun was beaming and the parking area was packed! Lou struggled to find us, but she got there in the end.


Gareth, Lou and myself kitted up and walked to the entrance. The entrance series was great and surprisingly easy to navigate, and before we knew it we were at the climb. None of us had a problem with it, well once Gareth and I transformed into human steps Lou didn’t have a problem. We signed the logbook at Cairn Junction and headed right towards Wonderbra. Once through Wonderbra we got to the “mud bank” and thought the left here was the left onto White Arch Passage, and carried on down the streamway.


Once we realised our mistake we turned around and headed back towards Tea Junction. We made good time through White Arch Passage, after a quick snack break at Tea Junction, and found our way into Lamb and Fox Chamber easily. We refilled our drinks at the cascade and then had another snack break at the cairn to Indiana Highway. Lou was feeling quite tired after the detour down and back up the streamway. Once we were ready to go again we were quite cold and tense. I don’t think this helped our nerves for the traverse. We climbed up the cairn and turned the corner into Indiana Highway, the mud bank was a challenge in itself! Once in the beginning of the passage we were all struck with its beauty, not that it’s decorated with formations, just the beautiful organic flow of the phreatic passage is enough! We quickly passed the side passages and round the tight corners to the start of the traverse.


I was first and headed into it around the first awkward corner to where it straightens out. I heard Gareth call and he was saying Lou was unsure about carrying on. We had a quick chat and decided amongst us we should just head back. On the way back we had a quick look at the side passages close to the start of Indiana Highway, we saw the fossil in the roof of the one chamber and couldn’t work out if we saw a shark tooth in the roof where you climb in/out of the side passage. On the way out we had no problems whatsoever and had a look in some side passages. We signed out on the logbook and headed back to the climb. We all had no problems climbing and route finding, and quickly found ourselves being soaked again on the final stretch. We got out and it was still a really nice day, so changing wasn’t too bad. We warmed up with a cuppa and headed on our way.

Agen Allwedd – Sunday 30th January 2022

Today Gareth and I headed back to Aggy, with the dig at the closest point to Daren Cilau as our target. As usual we were late leaving, it’s always one or the other of us, and it was a cracking day, crisp but sunny. We parked at Whitewalls cottage and were amazed how quiet it was, so we wasted no time and kitted up. Gareth dropped his phone and smashed his screen, he’s a tad clumsy.

We got into the cave at roughly 12:20pm and made good steady progress through the entrance to Baron’s Chamber, but about 80m into the entrance Gareth dropped his drink bottle and split it, so had to leave it for us to collect on the way out. We headed off to the right at the first junction along Main Passage, faultless past Bastard Passage and Flood Passage, but we had to search around for a while to find the entrance to the Second Choke. Gareth heading to high, and myself to low, eventually Gareth found it and we were off again. We stopped a few times here and there for Gareth to have a drink from his filter, which we always carry with us just for times like this. In no time at all we found ourselves at North West Junction, and we were off into a section we didn’t know, Main Stream Passage. The description we had warned of how slippery it is and as we entered it Gareth and I jokingly said “This is the lethal bit now isn’t it?” And with that I was almost flat on my back in the streamway, a very good save! It was steady progress along Main Stream Passage, it was slippery, no more so than any other streamway we’d come along already though. We passed Maypole Dig, but didn’t spot Chocolate Passage. I really liked the way the passage was changing to more of a phreatic passage now as we headed through Wormcast Passage to Deep Water.

We got to Deep Water and instantly before the water was even over my feet I was sinking in the silt, like quick sand almost, and I must admit it unsettled me a little as we were just about to wade into Deep Water. I went in first, with the floor slowly sinking away from under me, plumes of silt turning the black opaque water brown. I gingerly put one foot in front of the other and felt my way through as Gareth started to follow me. Gareth called out to say he wasn’t to sure about carrying on, we’d both spotted the undercut on the sidewalls and had images of Porth Yr Ogof’s resurgence. I spotted the water lapping at a bank in the middle of the passage, so called to Gareth to say it levels out. We pushed on through, only reaching waist deep, but immediately were confronted with another section that appeared the same. We stuck to the left hand side, a skinny, sloping, soft silt bank that slowly disappeared into the black opaque water, the silt wasn’t even visible. Once again Gareth said he wasn’t sure if he was comfortable with carrying on, but I said I’d push forward just to see how it felt underfoot. I got to just above my belt deep, the bank almost completely disappearing in towards the left wall, but continuing downwards, while it seemed to constantly be eroding from the silt dispersing under my feet, all added up to me backing out and agreeing we’re better off heading back the way we came. At the next club meet we’ll ask for advice and go from there.

The way back went absolutely fine. We stopped at North West Junction for something to eat, and I got quite cold while we stopped, but quickly started warming up again on the return journey. We got out at roughly 4pm to the sun just about to set, and as we were walking back we bumped into Paul, also from BCC on his way back to Eglwys Faen to retrieve his kids’ trainers. We got changed, had a cuppa and a pot noodle, then headed home after another great day in the great indoors.
