20 metres to the left of the boulder known as the "Medium Ball Boulder" in the Rockfax Lakes Bouldering guide, just left of the tree that separates the two blocks. This starts on the right of the main face and traverses left (not using the lip), and encounters a stopper move to a sloper at the half way point, after which nice moves give access to a top out aided by a "pancake flake".
