As you ascend, the terrain transitions to alpine waters and high tundra, with sections involving initial climbs and a steady ascent to near 11,000 feet.

From higher elevations, particularly Trappers Peak, you can enjoy panoramic vistas of both lakes and the surrounding Flat Tops. The area is also historically significant as the 'birthplace of wilderness' in the U.S.
