A challenging hike of more than 20 km, the bench above Rockbound Lake provides stunning views of emerald green Tower Lake, navy blue Rockbound Lake and the sheer walls of the "back side" of Castle Mountain. Larches around the lake turn golden in September, wildflowers and mushrooms offer botanical interest along the otherwise boring front section. And since this is not a highly recommended trail, you may just go most of the day without encountering anybody else!
