ADVISORIES:
[ACCESSIBILITY]: Unfortunately, the Cave is not handicapped accessible (there is some crouching required and no elevator). Guide dogs are NOT permitted in the Cave due to the presence of endangered species.
[COVID-19]: Face masks are no longer required but recommended if you have a pre-existing medical condition or are over 60 years of age. Masks are available for purchase in the Gift Shop.
[FLOODING]: Please call before visiting as the Cave is periodically closed due to flooding, especially during May, August and September.
