The Seaside Lagoon is a saltwater lagoon whose water comes from the ocean and is later chlorinated and then dechlorinated to ensure the lagoon only uses clean saltwater. This gives it a wonderful blend of being an ocean and also a pool with a lot of fun activities for children and adults. Besides swimming, you can play volleyball, enjoy a treat at one of the snack bars, build a sandcastle, or simply lounge around in the grassy area. Trained lifeguards are always on standby so the area is deemed safe at any given time.
