Upper Flood Swallet

Access

Upper Flood Swallet is an exceptionally well-decorated cave. Controls are in place to conserve the cave and to monitor the number of trips. Novices are not allowed.

Access is managed by Mendip Caving Group at the request of the landowner. Party size is limited to three plus the MCG leader.

There are many overhead formations which can only be avoided by crawling in the stream and suitable clothing must be worn - e.g. oversuit and furry, neofleece, or wetsuit. Gloves and balaclava, as well as food and drink, are recommended for longer trips.

A straightforward return trip to the Red Room takes about 2 hours. There are a few constrictions and one very wet section (the Lavatory Trap) which, depending on water levels, can be easily passable or almost a sump. On long trips, the level of the water in the Lavatory Trap can rise substantially, making it a sump on the return leg, which then has to be bailed.

Beyond the Red Room is a boulder choke containing 13 squeezes (the tightest of which is 23cm for a distance of 30cm) and an awkward rope climb. The choke is a natural feature which may be unstable and liable to movement. Cavers must take extreme care in this section, and understand that they pass the choke entirely at their own risk. A rescue dump is maintained in the Departure Lounge.

A return trip to the far reaches is not to be underestimated, and should only be undertaken by suitably experienced cavers. It is arduous and typically lasts some 6 hours with many obstacles requiring a good level of physical fitness, stamina and an awareness of cave safety. Participation on a trip is at the discretion of the Upper Flood Swallet leader.
