Whale Sharks at Gladden Spit
Whale Sharks in Belize at Gladden Spit
Join us at Gladden Spit during the annual snapper spawning aggregation, one of Belize’s most extraordinary marine wildlife events. We are scheduling Whale Shark & Spawning Aggregation Tours from April 20–30, May 20–30, and June 18–28, 2027, timed to coincide with the spawning activity that occurs around the full moon.
Gladden Spit is one of the Caribbean’s most important spawning aggregation sites. Thousands of cubera, dog, and mutton snappers gather to reproduce, releasing vast quantities of eggs into the water. This seasonal abundance attracts a remarkable concentration of marine life, including dolphins, bull sharks, blacktip sharks, Caribbean reef sharks, eagle rays, jacks, barracuda, and, occasionally, whale sharks.
While whale sharks are the stars of the show, their appearance is never guaranteed. In recent years, sightings have become increasingly unpredictable, and most tours have not encountered whale sharks. However, the spawning aggregation itself creates an underwater spectacle unlike any other in Belize. One guest described a whale shark tour without a whale shark sighting as “the best dive of my life” after watching dolphins repeatedly dive through schools of spawning snapper and surface nearby to feed.
During the surface interval, we snorkel a pristine reef area just inside the barrier reef. Because this site is visited only during the spawning season, guests often enjoy healthy corals, abundant reef fish, and a peaceful snorkeling experience away from the crowds.
If a whale shark appears, it is an unforgettable bonus. Regardless, Gladden Spit offers a rare opportunity to witness one of nature’s great marine gatherings and the incredible chain of life it supports.
Trip Plan
This is a two-tank boat dive trip that includes an authentic Belizean-style picnic lunch during the surface interval.In accordance with Belizean sustainable tourism practices, authorities allocate specific time slots for whale shark diving and snorkeling among licensed tour operators. As a result departure time from Placencia depends on the slot assigned. Travel time from Placencia to Gladden Spit takes about one hour and thirty minutes.
Whale shark diving is blue water diving with no visual reference – you cannot see the reef or the bottom. For that reason, it is important to keep a close eye on your depth gauge.
We work with a maximum maximum of 4 divers per divemaster to ensure safety and the quality of the experience.
Dive Sites
The wall here slopes down to 160 feet/50mt then drops off into the blue abyss. Diving is done in mid water at a depth no deeper than 80 feet/24mt in groups no larger than 12 divers with their dive masters. Divemaster and boat captains require annual training by Southern Environmental Association and special procedures are followed on this dive to ensure safety and to limit any harm that may be caused to the sharks.
