As the waves crash against the shore, the pressure of the water creates a powerful force that shoots up through the Blow Holes. Watching these powerful geysers is an amazing sight and one that shouldn’t be missed. Blow Holes is an area of natural rock formations located on the south side of Grand Cayman Island. As waves crash against the rocks, they create spectacular blowhole formations and spray mist into the air. The area is a popular spot for visitors to take in the view, take photos, and swim. Visitors can also take a boat tour to nearby Stingray City to observe the local wildlife.
