Daren Cilau / Ogof Cnwc

There are no formal access restrictions to this cave other than its notorious 550 metre entrance series. Nevertheless, please do not smoke or use carbide, and do not cause any degradation to the cave unnecessarily. Please take special care in Crystal Oxbow, where the crystals and calcite floor are especially vulnerable.

Ogof Cnwc / Old Prices Dig is an alternative entrance to the cave system, and is gated. To enter the cave via this entrance, the key may be obtained from Whitewalls from a member of Chelsea Spelaeological Society. A Ł10 deposit is required. Exit is possible without a key.
The dry connection between Ogof Cnwc and Daren Cilau is now fully open to cavers of most shapes and sizes. Please note, however, that the area needs to be treated with considerable caution until stabilisation work has been completed.

Please enter trip details either in the log book 20 metres inside the Ogof Cnwc entrance or in the log book at Big Chamber nowhere near the Entrance.

Fixed Aids

Fixed aids are installed at the main places where they are needed. However their integrity is not guaranteed and you use them at your own risk! Do not climb the 65-foot ladder in Preliminary Passage without a lifeline - and make sure you use the lifeline and not the hauling line.

Tackle Requirements

No tackle needs to be carried for the main routes, although some cavers may prefer to take a ladder for the Antler Passage climbs. An experimental ladder is currently in place on the 6 metre pitch between the Antlers and Man in the Roof.

Approximate Trip Times

These are for guidance, and are for fit, experienced cavers and do not include any allowance for route finding.

The White Company and Antlers	5 hours
Daren Cilau - Busmans - Ogof Cnwc through trip	5 hours	Note 1
Time Machine and Half Mile Passage	7 hours
Kings Road and the Sumps	8 hours
The Restaurant and Blue Greenies	12 hours	Note 2
The end of the cave	18 hours	Note 2

Note 1: See Ogof Cnwc information above
Note 2: Day trips to the Restaurant and beyond are a very strenuous undertaking and cavers should not over-estimate their capabilities when considering such trips.

Flooding

Most trips in Daren Cilau are possible in wet weather, although one short section of Bonsai Streamway can become neck deep! However, Ankle Grinder Bypass and Borrowed Boots Streamway do become impassable. Ankle Grinder Bypass floods without warning when the water backs up at the sump which usually takes the whole streamway.

For logistical reasons, there are two underground camps in the cave, known as Hard Rock Cafe and the Restaurant at the End of the Universe which are used on a regular basis. If you have not camped in Daren Cilau before but would like to do so, please contact Adrian Fawcett, Mark Lumley, Chris Seal or Charles Bailey for further information about HRC; Charles Bailey or Phil Rowsell regarding REU.
Please do not use camp equipment or supplies without prior arrangement, as most of it is personal property. However, please do feel free to write in either camp log book if you are passing through.

Most of the cave is still in a good state of preservation, but careless footsteps have taken their toll in Jigsaw Passage. Please respect the tapes.
Also, please take care not to disturb the permanent telephone wire in the entrance series. Report any damage to Adrian Fawcett.
