Epic Welsh Adventures in OFD

Club life: the most underground club in Wales


On the other side of the valley from Penwyllt, almost opposite the cottages, is the entrance to Dan-yr-Ogof. This is a fine and extensive system, and the river which flows out of Dan-yr-Ogof initially leaves the surface on the Black Mountain, more than two miles from where it can last be seen in the cave.

The entrance series of Dan-yr-Ogof is a show cave, but a 10 minute walk through the show cave leads to the start of the 'cavers cave'. Wetsuits are recommended as the Lakes and the Green Canal are cold and deep. Water levels in the Lakes especially are known to be very variable and can rise with little or no warning.

Control of caver access is through the DYO Cave Advisory Committee on behalf of the Show Cave owners. All parties (max 5 pers) in the cave must have a Dan-yr-Ogof Leader with them (called a warden) and have recognised caving insurance - but see the DYO CAC site for up to date access details.

And you will have to dodge the dinosaurs on your way in . . .

Ogof Ffynnon Ddu

Ogof Ffynnon Ddu, the Cave of the Black Spring, commonly known to the lazy or non-welsh as OFD, is the nearest cave to the club, lying almost under the cottages. There are 3 entrances to the system within easy walking distance of the cottage - the OFD I or bottom entrance, the Cwm Dwr entrance and the OFD II or top entrance.  Please see the access information for OFD to plan a trip.

For the ‘full’ experience without leaving your chair, look at the Virtual Tour at www.ogof.net 

OFD is Britain's third longest cave and at 275m deep is its deepest. The through trip from the Top to the Bottom entrance remains a classic in the UK, and its approx. 61km of passages provide everything from huge chambers, beautiful formations, to yawning chasms and thundering river passages.   The routes though the cave are too numerous to mention, but the simplified survey above locates some of the main points.  Copies of the full survey are available from SWCC HQ.

Be aware that the Mainstream and some other parts of the cave are prone to flooding, and in any event a journey down the Mainstream is long and cold and wet, so go prepared.

At the club's 75 anniversary a major project was launched to replace the roof on the club HQ and thus secure it as a base for caving in South Wales for the foreseeable future. This is a major undertaking that will involve the club in fund raising and planning activities for the at least the remainder of this decade. 

Roof Replacement - Savings

March 2018 update

January 2018 update

Planning: We have submitted a pre-planning application to the Brecon Beacons National Park who have indicated that their preference is for the chimneys to remain. This is a non binding and without prejudice opinion was made on the basis of drawings and photographs supplied by us showing the HQ with, and without, the chimneys. There was no site visit. Whether we accept this opinion is up to us but may in part be dependant on the cost.

Design & Construction: We now have a very robust design which has been produced by a structural engineering company and also discussed with a Welsh based construction company who specialise in heritage roofs. They have visited Penwyllt, inspected the roof internally and had preliminary discussions with us. They have taken away the proposed design with a view to coming back to us early in 2018 with an indicative cost. I must stress that at this stage the design is not final. It has been produced as a basis for discussion and to  enable us to get some idea of the likely construction methodology, constraints and costs. 

Financials: The ring fenced roof fund currently has a balance of just under £22K with a likely annual transfer of a further £10K from the club's operating account due in January. As described in the prospectus there is planned giving scheme where by members can commit to a periodic standing order of any amount the chose direct to the ring fenced roof fund. As soon as we have a better idea of the costs we will be raising the profile of this and other the fund raising 'opportunities'.
