5m. Originally graded Mod however by popular consensus the grade has been changed to 4a, it still gets it's star though as its a great litle route.

I soloed just about every route at 4b and below, and this was almost the hardest. Surely Mod must be a misprint, have the grades of this and Friendly Wall been transposed?
