Stand start on the neatly protruding slab on the right of the face. Climb directly up through the series of sidepulls, towards the dark varnished flakes at the lip. Trending right early eases the difficulty.

First bouldering trip with my 8 month old son - didn’t get a whole lot of climbing in but still got to work out this thing - building up the feet is what unlocked it for me, then felt very doable - repeated it the next day for the send vid
