Best Times to Visit Morning Visits: The first tours of the day are usually less crowded, giving you a quieter and cooler experience underground.

Accessibility & Inclusion

Stroller Access: Strollers are welcome throughout most surface areas. However, due to the twists and bends of the cavern pathways, strollers are not permitted on tours. Stroller parking is provided nearby.
Sensory-Inclusive Support:
Natural Bridge Caverns is certified sensory-inclusive, a first for a commercial cave in the state. In partnership with KultureCity, staff receive special training to assist guests with sensory sensitivities. The venue offers sensory bags equipped with noise-canceling headphones, fidget tools, and cue cards, as well as a quiet space for those needing a calm retreat.
Service Animals Only:
Only service animals that comply with ADA standards are allowed inside the caverns and buildings. Pets are permitted in public outdoor areas, as long as they are leashed, managed responsibly, and not left in vehicles. Crates are also available for temporary use on a first-come, first-served basis.
