The Chattanooga Grotto is a local organization of cavers associated with the National Speleological Society.
The Chattanooga Grotto meets on the first Monday each month at the Outdoor Chattanooga building in Coolidge Park which is located at 200 River St. The meetings begin at 7:00 Eastern. Meetings usually consist of a short business meeting, and a cave related program. Programs vary from guest speakers to slide programs on caves and caving. Cave trips are scheduled throughout the month and the meetings are the best time and place to find out when trips are occurring.
The Chattanooga Grotto Facebook Group is very active and a great place to meet the local cavers and get involved.
