I am interested in organizing a group booking for the 'Xtreme' trip through old underground mine workings organized by Go Below. This is an all day guided trip which involves ledges, bridges, zip wires (1-3), abseils (1-3) and lit only by head torches. There is an excellent website giving lots more details and photos. The cost would be £59; less 10% if I can muster 9 others. The meeting venue is Tanygrisiau Station and I am looking at Sunday, 23/10 or Sunday, 6/11. Please ring me on 01286 660370 before 31/08/16 if interested.
