About this site
Tarzan Cave lies along the coastline of Guam in the western Pacific, an island territory with fringing reef systems shaped by volcanic and limestone formations. Cave and cavern sites on Guam typically formed within the island's uplifted limestone terraces, which honeycomb parts of its coast.
