Tours depart daily from late May through September, with peak season in July and August. Most tours leave at 08:00, returning around 14:00. Requires a 1,5 - 2,5-hour bouncy boat ride, depending on the weather, but passes dolphins, flamingos, and maybe turtles and manta rays. Ceviche lunch included, and snorkeling at a well-used reef with potentially cloudy visibility. Small and cheap tour companies only allow visitors two times in the water with the sharks, no touching is allowed. Standard shared tour price is US$150-170 (Aug 2023), although cheaper deals may be found. Anyone charging less than the standard rate may not be a completely legitimate business and thus may not be following all regulations designed to protect the whale sharks.
Cool off in the fresh water cenote. There is a palapa (gazebo), bathroom (M$5 for use) and a stand selling beers, water and small snacks. It is M$25 per person to enter the cenote area.
