Sequoia National Park is known for the Giant Forest and beautiful granite cliffs, yet there is much to be seen below ground as well. Crystal Cave is an amazing space where the water has polished the marble surfaces and the different stalagmites and stalactites form other-worldly formations. This Ranger-led tour is fun and informative. The trail down to the cave is downhill, so make sure you bring some water, especially in the warmer Summer months, for the hike back up. It’s an inspiring place to wander. Get out and #FindYourPark.
