We are a group of individuals from the Philadelphia area who like to drive 14 hours (sometimes less) to crawl around and get wet and muddy in caves. Many grotto members are active in other outdoors activities, such as backpacking, white water rafting, hiking, sailing, rock climbing, and mountaineering.
The Philly Grotto emphasizes the National Speleological Society motto:
Leave nothing but footprints, take nothing but pictures, kill nothing but time.
We are a conservation-minded organization interested in educating people about the underground wilderness that we love.
