Swim with whale sharks, the world's largest fish, and see other amazing sea creatures such as sea turtles, manta rays, and dolphins in the waters where the Caribbean meets the Gulf of Mexico. Despite its name, the 45-foot-long (14-meter-long) whale shark is an animal that allows for an up-close experience with your expert bilingual guide. After a light breakfast, head out from Isla Holbox to swim with the whale sharks, then back to the mainland to snorkel and enjoy fresh ceviche made with the day's catch. Snorkel gear is included along with a light breakfast, lunch, beverages, and ceviche.
