Goblin Valley State Park is home to an expansive cavern with skylights and ceilings 70 feet high! Join them for a three-mile round trip backcountry adventure to this hidden treasure that only a handful of visitors have ever seen. One liter of water per person is recommended. As with a descent into any unimproved cavern, some rock scrambling is involved. Meet at the Carmel Canyon Trailhead in the observation point parking lot.
