Climbs through several bulges before finishing on a slabby face near the top of the Castle. Shares a first bolt with Storming the Castle then heads right. Find your way over a strangely rounded bulge halfway up then pull right onto the giant flake above the roof traverse on Grappling Hook. Use slab technique to reach the anchor or, if you prefer, use the arete to the right.
West side of the Castle. Look for a small clearing with a bolt above. Hunchback heads right after the bolt.
6 bolts.
