Forget about the trees! Explore Crystal Cave in Sequoia National Park

Sequoia National Park is famous not only for its giant sequoias, but also for Crystal Cave. Of the 240 or more known caves in the park, only this one is open to the public (by guided tour only). This marble karst cave is full of natural crystal formations along its 4.8 - 6.4 km (3 - 4 mi) stretch. You'll be amazed by the beauty of this marble-decorated cavern with its variety of formations, subterranean streams and curtains of stalactites.

Crystal Cave is located off the General’s Highway in Sequoia National Park, and a half-mile hike is required to get to the cave entrance, but the view is totally worth it. For other hiking options, the park contains numerous mountains, lakes, waterfalls; and visitors can choose to take a guided tour or pick their own route through the park.
