Blue Hole is a famous dive site in Indonesia that features a large cave starting at 127m/417ft. The cave itself and its entrance are quite wide and lead to a dome with many small pinnacles, a healthy reef, and an arch. It is very dangerous to dive under the arch, and only highly experienced technical divers and deep divers can do it.
