Founded in 1952, The Central Ohio Grotto is a group of cavers from the Central Ohio area.   We promote fellowship among cavers and the ideals of the National Speleological Society (NSS).

Interested in becoming a member of COG?  We’re happy to have you join our fun family of cavers.  Our admission process is easy but you don’t have to be a member to attend meetings or join us on our caving trips.

Join our Facebook group for realtime updates, meeting notices, trip planning, etc.  http://www.facebook.com/groups/centralohiogrotto/

The COG also has a mailing list. To subscribe, send an email to COG@ontosystems.com with the subject subscribe.
