Studying, exploring, and protecting caves
Since 1941 the NSS has been at the forefront of cave science, conservation, and exploration. Join our 8,000+ member community and come caving.
Since the 90's, The Virtual Cave has provided a definitive visual reference for all things found in caves. Cave formations, also known as speleothems, can take many forms besides the familiar stalagmites and stalactites. See the amazing variety and learn the science behind how speleothems take shape.
Come caving with us!
Our 250 local chapters - known as Grottos - provide the perfect opportunity to start caving. Find your Grotto and start caving.
