A valley floor crowded with thousands of mushroom-shaped hoodoos - 'goblins' - of soft Entrada sandstone, unlike anywhere else on earth. Visitors are free to wander off-trail among the formations, making it one of the most family-friendly playgrounds in the state. The surrounding San Rafael Swell offers slot canyons like Little Wild Horse just minutes away.
