Snake Dike is this amazing ten pitch 5.7 slab climb that goes up the side of Half Dome. We (me and Dan) walked up the night before and camped at Little Yosemite so we could get an early start and beat the crowds. The climb follows a granite dike line up the slabs and the only gear is the bolt belays and couple of bolts in between them - 20m runouts are mandatory. The climbing, though exposed, is pretty easy (which is lucky) and you finish the route on the summit of Half Dome with some stunning views of the valley. Of course it's still not finished as you then have to down climb the cables and walk back out.
