A strenuous hike. Due to construction on the east side of the park, this loop should be started from the main parking area on the west side. Much of this trail follows the Chalone Creek bed and is marked by rock cairns. Makes a loop by combining with the Old Pinnacles and Balconies Trails.
A talus cave, formed from falling boulders creating a "roof" over a narrow canyon. This cave is one of the most popular in the park, and can be visited from either side of the park by following the Balconies Cave trail. A flashlight is required through the cave. The cave is dark, wet, and some scrambling over rocks is required.
Portions of Bear Gulch Cave are closed throughout the year in order to protect a colony of Townsend's Big-eared bats; the cave is closed entirely from mid-May through July. A flashlight is required through the cave.
