Welcome to the Philly Grotto!

Philadelphia Grotto is a group of enthusiastic cavers who are interested in the world underneath the earth. We travel all over the world in our search for caves and karst. Caving is not only about sport, it also involves learning about geology, hydrology, microorganisms that live in total darkness. This science learned from caves helps our planet grow every day.

Our goal is to promote interest in and to advance the science of speleology, to promote conservation of caves and safety in their exploration. Educate and support those that have the same interest that we do.

Come join us for our monthly meetings to learn more about how can you be involved in the Philadelphia caving community!
