Castaway Island's Tidal River

Think Lazy River but with Waves!

The centerpiece of the all new Castaway Island is the Tidal River. One of only a few tidal rivers ever created, guests enter a refreshing zero-entry wave pool before making their journey to the entrance of the river. As you glide past the Tiki Guardian, waves are formed every 10 seconds propelling you through a tranquil island oasis around our Slide Island.

Proper swimwear required and guests under 42″ in height must wear a complimentary life jacket.

Castaway Island's River Slides

Python, Anaconda & Constrictor

Take the River Bridge over the powerful Tidal River to get to Slide Island. Guests can walk up the 62′ tower to find three very different types of water slides. One slide is entirely open at the top so you can still get your sun tan while soaring down to the run-off pool. The second slide is entirely enclosed so you feel like your traveling through a dark tunnel in the tropics. The third slide gets wide, then skinny, then wide, then skinny, causing you to whip through the experience.

Proper swimwear required. Minimum of 48″ in height to ride. Single person uses single tube with 300lb max capacity and 2 people use double tube with a 400lb total max capacity.
