Visit the whale sharks at Gladden Spit, the most easterly part of the Belize Barrier Reef that is part of the Gladden Spit and Silk Cayes Marine Reserve. It is a spawning aggregation site for many different tropical fish species including the cubera, mutton, and dog snappers which produce tons of spawn. This spawning occurs around the full moon to last quarter during the months of March to June. This is what attracts the whale sharks at Gladden Spit near Placencia in Southern Belize. Whale sharks are the biggest fish in the ocean growing up to lengths of 60 feet/18 meters and are gentle filter feeders that eat minute plankton and spawn.
We are scheduling whale shark tours April 10 to April 20, May 10 to May 20 and June 9 to June 19 in 2025 but I need to caution you. In April and May 2024, there were no whale shark sightings. In April 2023 there was one whale shark sighting and no whale shark sightings in May or June. In 2022, we did one whale shark tour in April and two in May (saw lots of bull sharks but no whale sharks). In 2021 we did three whale shark tours and saw a whale shark on one of them. In 2020 we did not do any whale shark tours due covid-19, although there were sightings by fishermen at Gladden Spit. For the first time ever, in 2019 there were no whale shark sightings. In 2018 we saw whale sharks on less than 1/2 the days we went out.
While appearance by whale sharks is uncertain, you can certainly expect to see black tip reef sharks and bull sharks and dolphins who come to feed on the spawning aggregation of cubera snapper, dog snapper, mutton snapper and horse eye jacks. One of our guests said a whale shark trip with no whale shark sightings was the best dive she had ever done – dolphins were repeatedly diving for snapper and returning to the surface to eat them right beside her. We snorkel during the surface interval/lunch break in an area just inside the barrier reef – lots of reef fish and healthy corals in this area which is normally only visited for three 10-day periods in April, May and June.
Trip Plan
We do two excursions into the whale shark zone with an authentic Belize style picnic lunch on the boat. During the lunch break we snorkel in an area just inside the barrier reef – lots of reef fish and healthy corals in this area which is normally only visited for three 10-day periods in April, May and June. The lunch break offers an excellent opportunity for snorkeling just inside the barrier reef.
In accordance with Belizean sustainable tourism practices the time slots for Whale shark diving and snorkeling are allocated to dive and snorkel tour operators. Accordingly, our departure time from Placencia is dependent upon the assigned time slots. The travel time from Placencia to Gladden Spit is one hour and thirty minutes.
*Note that the minimum age to go to the whale shark zone is 14
