Swim with the biggest and most gentle shark in the world, an experience you will never forget! These gentle giants meet in large numbers to feed in the plankton-rich waters of Bahia de La Paz. There are whale sharks almost year round, but the highest concentration of individuals is between November and April. This natural phenomenon gives people an opportunity to experience one of the most exciting encounters between people and nature. Although Whale Sharks are large in stature, they are harmless, they have no teeth and they eat microscopic plankton and feed filtering water while gulping.
