The Ansel Adams Wilderness Parker Lake hike is easy access for an alpine lake, a walk surrounded by pine and aspen trees. Fall can be especially spectacular when it is filled with foliage. The hike is nearly four miles, round trip. Parker Lake Road, a bumpy dirt road off the June Lake Loop, will take you to the parking area and trailhead. Begin the hike in the sagebrush at the bottom of a hill. Looking back at a spectacular view of Mono Lake, the trail levels out through a forested area, continues along a shady creek, and ends at beautiful Parker Lake. The hike itself is very rewarding, and the lake a gem of the Eastern Sierra.
