Left hand of trio of routes on large 'Matterhorn' boulder. Hard start, fun finish, no lower off(traverse right to use the one from the middle route). Due to the position of the 2nd bolt it is extremely difficult to retreat at this point, as the rope gets jammed between the krab and the rock on the lip, so worth taking a quickdraw with a sling long enough for the krab to hang over the edge (20cm should be enough). Alternatively stop being a wuss and keep climbing.
Graded 6b in the online PDF guide, the start might just about warrant 6a but no more.
