At the base of Tumwater canyon, the Labyrinth requires a bit of a hike but has a number of enjoyable climbs up the hill. The pullout is 0.5 miles from Icicle Junction on the left side of the road. Walk a little west and up the well beaten trail. The trail should be very clear. It is pretty steep and takes about 10 minutes to get to the first large boulder (Roses/Warmup) but the climbs are pretty well clustered from there.
