Although having been caving in the South Wales caving region since 1994, with trips into most of the major cave systems, I had never ventured into OFD1. This was rectified with a trip with three other BCC members, for two of whom, this would also be a first visit. The recent weather had been predominantly torrential rain and so we doubted that the Main Streamway would be accessible and so we decided to content ourselves with a potter around the passages that lead up to The Step where the streamway is usually entered. I also wanted to see what my Christmas present; an Olympus Tough TG4 camera was capable of, so had packed it as well as a tripod for the trip in expectation of encountering some very photogenic cave passages.

The rain had left off on the Sunday morning and we arrived at SWCC headquarters at a reasonable time and filled in our ticket and received our key for OFD1. Jumping back in the car, we drove down to the lay-by to change and proceeded to the entrance. The cave is entered via a ladder that takes you down to a heavy steel door, that when opened allows a huge draught to flow, that gives some expectation of the size of the cave to be found within. A second ladder then drops down you into the cave itself.

We first decided to have a look at Gothic Sump so followed Gothic Passage to arrive at a most dismal looking sump. Foam marks on the walls indicated the depth to which the water had risen, which showed that the sump had backed up to a considerable height in Gothic Passage itself. Back at the ladder, a short section of stooping passage took us to Main Passage in the Cyril Powell series. The first evidence of an attempt to open the cave up as a show cave is found here with the stream running down the right hand side of the passage in a man-made channel. A junction is soon reached with a large passage to the right being the main way on but we elected to have a look at the smaller passage straight ahead first and find Skeleton Chamber. A quick stop for some photos of a formation and an attempt to photograph some water splashes (I need to work on this) and Skeleton Chamber was soon reached. This is entered by dropping down through a hole into a chamber that runs perpendicular to and back under the passage we entered from. It was here that the original explorers found a human skeleton, hence the name of the chamber. There is a tale of an itinerant castrator that visited the cave by some lost entrance. He walked off into the darkness with a burning torch, blowing a bugle never to be seen again. One theory is that the skeleton belonged to this man but it could also be a Bronze Age burial. Whoever he was, his bones now reside in a cardboard box in Cardiff museum. Turning our lights off for a brief “Derek Acorah” moment produced the expected result of absolutely nothing happening and we then climbed back out of the chamber and proceeded to Pearl Chamber for a couple of photographs before returning to the junction.

Following the other passage from the junction took us past the Cathedral and the Font to Flood Passage and on to The Toast Rack. Above The Toast Rack, more fine passage was followed that took us back to a roaring Main Streamway and then Traverse Passage. A quick crawl around the passages at the top of Traverse Passage and then we headed back down towards The Step which is the usual point of entry into the Main Streamway. Here the amount of water in the stream and the sound was quite staggering and it was obvious that any attempt to enter it would not be sensible so we went back a short distance to the short climb up to Column Passage, another fine passage that leads to a small chamber containing a pool and a large column formation, The Column. The description of this place on the virtual tour at Ogof.Net says that the pool has delicate calcite plates growing on the surface and that the pool should not be entered. Sadly, there was no evidence of these.

We went back to the step and took a few more photographs before exiting the cave after a thoroughly enjoyable trip. We didn’t cover a huge amount of ground but to me, these are often the more enjoyable trips, where you get to take your time and really look at everything rather than speeding past on the way to some other goal. OFD is a very complex cave system that offers a lot and I feel it will repay you greatly if you take the time to explore a small part of the system before later moving on to trips further into the cave.

The weather had taken a turn for the worse after we exited and so a rapid change in the lay-by was required although I missed a great photo opportunity when Zeb stripped off and ran to the passenger door of the car where his dry clothes had been left, only to find the door still locked. A naked Andrew Zerbino hopping about covering his modesty is not a pretty sight. I suppose I could have been quicker with unlocking the door but we were all giggling too much. A couple of pints in the Ancient Briton in time-honoured fashion rounded off a very enjoyable first trip into OFD1.

Early on a Sunday morning at the beginning of December I drove from Abergavenny about 50 minutes through the beautiful countryside around Brecon en route to Penwyllt in the Swansea Valley. Penwyllt is the headquarters of the South Wales Caving Club who are the gate keepers for the Ogof Ffynnon Ddu cave systems. There I met up with Huw and a new man to the club named Lee. Lee’s other half Carolyn had meant to come but after doing her first BCC trip into Aggy earlier that week she was still a bit stiff and decided to give this trip a miss.
We changed into our gear and Huw grabbed the key and signed us out on SWCC’s caving board. Cavers on the whole are very enterprising with their approach to gear, producing bespoke and homemade/altered gear and Lee was no exception. He came to South Wales from the peak district and a climbing background, having done some caving, where he claims that he didn’t have much use for a helmet. The helmet he pulled out of his gear bag was an impressive creation. He had adapted a helmet with black duct tape to hold several head torches.
We walked down the hill to the cave entrance, about a 20 minute walk. This was a new way of approaching the cave for Huw, who said that years ago you had to drive down the hill, park and use someone’s drive, but recently the right of access and land had been secured by the club allowing us to walk down from the club.
We approached the entrance, descended the ladder and opened the gate to enter OFD 1. The plan was to do the round trip. Huw had printed out the surveys and route descriptions and highlighted our route. He gave me the opportunity to lead the trip and do the route finding. We got our bearings and set off through the lower section which had been set up to be a show cave with concrete floors and railings, now gone. We made our way to the Toast Rack which is a junction, either going straight on through Pluto’s bath or up the fixed step ladder that takes you up over a six foot smooth flowstone step. We went up and came shortly to another junction, where we took a right under some fine curtains and headed to the Step, which was a nice series of steps down into the main Stream Way. The Stream Way was brilliant, a long winding passage with rushing water carving great shapes and scallops into the rock. Crossing the pots is the main hazard at this water level and is fun because you have to balance on a rolling scaffolding bar which is attached on the upstream end. None of us swam, but we did fill our wellies! We made our way along to Lowe’s Chain which is a smooth 4 meter high wall with two fixed ropes hanging down it. We passed this and went on up the stream to a waterfall and the end of the passage, where I climbed up over a natural stone bridge to have a look at the entrance to the Waterfall series. It was a precarious climb and I wouldn’t recommend it to anyone with a fear of heights or a priority on self-preservation. I carefully climbed down and we made our way back to Lowe’s Chain where we climbed out of the Stream way. The climb wasn’t too tough, but this could prove to be the most difficult part of the trip for some cavers.
This took us up into the Rawl Series, a dry blocky series of passages, chambers, and chokes where Lee discovered the value of wearing a helmet. The cave here is similar in character to OFD 2 further up the hill. The route took us up and back around on ourselves until we arrived at Pi Chamber where we went left, and I found the way on behind a boulder which dropped us steeply down a small phreatic tube (a long way down surprisingly) to the beginning of the bolted traverse 50 feet above the Stream Way. If you don’t like traverses, cow’s tails are advised to attach yourself to the cable, but it is a wide and flat ledge that can be done without them. The start is the scariest bit because you have to slither over a polished bolder and carefully get your foot on the ledge beside the drop! I managed without attaching myself to the cable, tucking my elbow over the cable and slithered along the wall when the ledge narrowed!! Exciting!!!
After the traverse the passage meanders until you pop your head out of a dig and then crawl back to a recognizable junction where we saw the hanging curtains earlier. We had finished the round trip and done if fairly quickly so we headed back down past the curtains and scrambled up a smooth flowstone climb on the left and made our way to along Column Passage to The Column, which is well worth the visit. We then went back down to the stream to a fork which lead us back up to the Toast Rack, this time crossing Pluto’s Bath. I successfully crossed it without getting soaked due to my long legs. Lee got a bit wet!
We made our way out and back up the hill, to the showers and changing facilities at Penwyllt. It was a great trip and you can see why it’s a classic caving must do for any aspiring caver. It takes less 4 hours, its good practice for navigating, it has every variety of cave challenges, none of which are too extreme or unpleasant and it’s stunning. It’s a lot of fun and having a warm shower and a roaring fire to follow it up makes a perfect day.
