"Grunt" is the obvious zig-zag corner on the far left of the main face. This route is 18 meters long with an interesting mix of an arete, an offwidth crack, and a little face. It is toprope accessible.
Approaching the crag from the parking area scramble up the scree slope towards the left side of the clean face.
The first 15 meters are straight forward. The crux is the last 3 meters where this off-width crack makes a somewhat inverted right-hand angle. It is very conducive to the barn-door effect.
