The Cayman Islands are a group of three stunning islands in the Caribbean, and vacation there will provide pure escapism owing to the pristine seas and gentle powder-white sand beaches. Even though it would be easy to just relax in one of the opulent resorts, there is plenty to see and do if you want to venture out further. For example, the Cayman Islands are known as one of the best diving destinations in the world, with more than 300 dive sites that range from sunken ships to snorkelling walls.
