2. Cathedral Lake – one-way mileage is 2.5 miles. Difficulty level is easy to moderate.

3. Mount Tallac – one-way mileage is 5 miles. Difficulty Tallac is part of Desolation Wilderness and the tallest mountain on the lake’s immediate shoreline. At 9,738 feet, the mountain stands as a commanding landmark, and it is a continual draw for hikers in the summer and back country skiers in the winter.
