Prepare for the Cave Tour
The cave temperature is a constant 41 degrees F (5 degrees C), so warm clothing is recommended. Wear good walking shoes, as the trail surface is uneven and slippery. Per the NPS, no flash lights should be brought on the tours. Cameras are ok. No tripods are allowed in the cave.
Children on Cave Tours
Children must be at least 42 inches tall and be able to climb a set of test stairs unassisted to go on the basic tour of the cave. Children may not be carried by any means through the cave, and child care services are not available at the monument. Ask about special tours for small children. A parent or guardian must accompany the child at all times.
