two teams with members I know well went last year and were not overly inspired regarding the karst potential I gather. Best to speak to Pete Talling and Imogen Furlong (aka MoMo). the Wessex and CPC also held a joint exped there last year, not sure who was on it.
From what I have heard, cave potential is next to nil and they were sent to areas that had already been visited. Go climbing instead, was the overriding message.
