We took a Carnival cruise and journeyed to Nassau Island in the Bahamas, there we visited the world famous Atlantis Resort and Waterpark. Among the most popular and scariest waterslides is the Leap of Faith, which is a 6 story drop that ends in a tube through a shark lagoon. My 2 kids age 12 and 13 took the leap and had a blast!
For those who are looking for a less extreme version, you can go on the Serpent Slide which requires 1 or 2 passengers to sit on an inflatable tube and go through a dark windy slide that ends with floating through the shark lagoon where you can take time to enjoy the sharks swimming all around your view.
Atlantis is filled with many other pools and slides of various shapes and sizes and includes a younger kid waterpark. Another hidden gem is the adjacent beach which features white sands and clear aqua blue waters. Life vest are provided here and if you have snorkeling masks you will be able to spot tropical fish in the waters too.
Tip: the admission price is expensive if you are not staying at the hotel, but you can look for some 3rd party vendors who sell the tickets online for a discounted price.
