Trail Details

First read the informative signboards on the south edge of the lake by the parking lot. They examine Castle Lake’s natural history and discuss how scientists study the lake. The short trail leaves from the northeast end of the parking lot (on the right just past the restroom as you drive in). It heads along the west shore of the lake and allows you several opportunities to reach the water’s edge for a refreshing swim or a contemplative sit.

See separate entries for hiking to Heart Lake and to Mount Bradley Ridge.
