Rock Lake is an archetype, a quiet little body of water deep in the woods that looks like any one of thousands of others in the Adirondacks. But that's a great part of its attraction. What you see and learn at Rock Lake won't stay at Rock Lake. You'll be pleased to take your know-how elsewhere. The trailhead is 5 miles south of Blue Mountain Lake on Rt. 30. Round-trip walking distance is about 1.6 miles.
