Composed of limestone rock, the rugged terrain of Devil’s Bridge is the result of millions of years of ancient reef formation. For hundreds of thousands of years, the Atlantic’s waves have crashed into the east coast of Antigua creating a natural arch, or bridge. Numerous geysers and blowholes surround the arch as waves continually break against the coastal rocks.
Devil's Bridge National Park is located on a headland on the eastern end of the land. The area was legally constituted as a National Park in the 1950's.
