Start on the left of the arete and trend up and across to the right side of the arete on small edges. Don't be afraid to go too far to the right as this climb seems to wander a little. The moves on this route can feel awkward and burly for an .11c. While not steep, this climb can leave you guessing. No real distinct crux on this route, but climbing eases up a bit after the last bolt.
From right to left, Matilda is the last route on the wall before you turn the corner and enter the cave.
4 bolts plus the chains.
