Tormore Group - Cnoc Na Mara

Whilst it might seem like an amenable grade and reasonable length, this is a serious adventure on rock that is loose in places with limited reliable protection in places. Expect a long day our for this adventure! The route takes the landward facing ridge to the summit. You will need a small boat or canoe to get to the base and ideally a very calm sea in order to make a reasonably safe crossing. Expect a complicated descent requiring some down climbing and abseiling.

Approach & Descent Information

Drive the 22 kilometre c class laneway from Ardara to the road end at An Port, the gateway to Irelands last great wilderness. Fom here on foot, follow the clifftop path for approx 2 kilometre to an outstanding viewpoint overlooking Glenlough Bay, Irelands largest raised shingle storm beach. From this viewpoint descend the very steep grass/scree slope for 200 or so metres and abseil from the two peg belay to the Entrance to Shambala storm beach. From the beach it is a 125 meter sea passage to the base of the stack.
