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.

Cano, the Goddess of Tides and Queen of Water reigned supreme. While traveling her coastal domain, a vision appeared in a tide pool telling her that her world would soon be lost. She was to take her three children, Earth, Air, and Fire, to a secluded oasis. Cano touched her finger to the sea and created an island. Over this island she placed Kanaloa, an octopus of protection. She then captured the sun and placed it beneath the octopus to create paradise.

Cano needed to send word to her three children to come to the island. She carved directions to this new home on the Tablet of Earth, the Tablet of Air, and the Tablet of Fire.

Cano, Earth, Air, and Fire all lived on this island for thousands of years in peaceful harmony. Cano created a water oasis, Earth created beautiful grounds, Air created a summer breeze, and Fire created the food that would sustain them forever.

Thousands of years later the tablets were found. Archeologists have been working for centuries to decipher the location of this cast away island and they are close. Kanaloa and the Tiki Guardians will ensure this oasis is preserved for all of time.
