Descend into a vast underground maze known for calcite crystals, intricate passages, and continuing exploration.
Why it belongs on the route
Jewel Cave National Monument protects one of the longest mapped cave systems in the world. Guided tours reveal portions of a much larger underground network filled with calcite crystals and other cave formations.
Because tour capacity and access can be limited, Jewel Cave deserves advance planning. Travelers leaving Pierre should treat it as part of a Black Hills overnight itinerary, with enough time for check-in, parking, safety instructions, and changing mountain-road conditions.
