Blue Lagoon Island Do you want a private getaway or an island all to your own (if you can afford it)? If you have that inkling, then, it is suggested that you visit the Blue Lagoon Island located a few miles away from Nassau. Blue Lagoon Island is one of the most popular island and tourist attractions in The Bahamas. They used to call it Salt Cay back in the 19th century because pirates used to utilize the island for its “salt” properties.
