Cathedral Reef (Bermuda)

A popular dive site for tourists, this reef is named for the huge underwater dome you can swim down into at around 45 feet. It consists of a series of breaker reefs that have created a group of connecting caves, overhangs, and canyons. They’re relatively easy to swim through - but disorienting if you’re not used to cave diving. The top of the Cathedral has several holes where shafts of light penetrate the darkness of the cave in beams of holiness.
