About the Grotto
The District of Columbia Grotto (DCG) is the local chapter of the National Speleological Society (NSS). Organized caving began in Washington DC in 1939 and we consider our grotto to be the oldest caving organization in the United States.
We bring unique people together to explore caves in the region. The Grotto promotes cave exploration, project caving, new cave discovery and conservation. We take pride in transforming new cavers into experienced leaders.
Join DC Grotto
Membership with the Washington DC Grotto opens a door to true adventure. Caving is physical, claustrophobic, muddy, awe-inspiring, and unbelievably rewarding. The DC Grotto only caves in wild caves, no pre-hung lights, no sidewalks, and no tourists. Membership offers an experience unmatched in Washington DC.
