LAUCALA ISLAND: A PERSONAL SUBMARINE

In 2014, the private-island property of Laucala Island in Fiji became the first resort in the world to offer visitors a ride in a custom submarine called the DeepFlight Super Falcon.

From domes that offer 360-degree views, you can check out more than 1,500 species of fish and colored reefs. The best part is that the activity is included in the nightly rate for your stay.
