Pinnacles National Park, California
Below: Rock "pinnacles" near Machete Ridge.
Below: We hiked through the Balconies Cave. This cave was formed by large (really large) boulders crashing down from above, leaving narrow passageways and completely covered passageways that were pitch dark inside. We had to use flashlights to navigate some parts of the cave. Here you can see the entrance gate to the cave which is locked sometimes to allow the bats to raise their pups undisturbed.
Below: This is an 'outdoors' section of the Balconies Cave trail.
Below: We watched two rock climbers ascend a steep rock face.
Below: One of the huge, impressive boulders laying around.
