Castaway Island Tidal River

Enjoy the relaxation of a lazy river with the added excitement of rolling waves for a refreshing aquatic adventure.

It follows a similar flowing pattern to that of a lazy river: however, waves are added into the mix every 12 seconds. Guests enter through the zero depth entry and must be at least 42 inches tall if opting not to wear a free life jacket. It is also recommended that all weak or non-swimmers wear a free lifejacket.
