Whitestone Cliff, tucked away in the hills north of Waterbury, has seen many decades of climbing activity and has several good routes, yet remains relatively obscure. The rock is solid and provides several crack, corner, face, and slab routes (trad and TR) spread out over the four main areas: The Right Side, closest to the approach, The Main Slab, the largest area, and the Lower Cliff and Lower Lower Cliff, which are much less frequently visited. The approach trail follows the blue-blazed old road for a quarter mile or so before turning right, still on blue blazes, and down on a trail to a stream crossing. When the trail becomes very rocky and the cliff loom left, descend left along the base of the cliffs to reach the Right Side and Main Slab areas. There is a path on the far left that loops back up to climb to the summit, which affords good views due to a small fire in 2010 that killed the trees there.
