About Whale Sharks Gladden Spit

Visit the whale sharks Gladden Spit — the most easterly part of the Belize Barrier Reef within the Gladden Spit and Silk Cayes Marine Reserve. Notably, this is a spawning aggregation site for many tropical fish species, including cubera, mutton, and dog snappers. These fish produce tons of spawn.

The spawning occurs around the full moon to last quarter during March to June. As a result, it attracts the whale sharks to Gladden Spit near Placencia in Southern Belize. Above all, whale sharks are the biggest fish in the ocean, growing up to 60 feet (18 meters). They’re gentle filter feeders that eat plankton and spawn.

We schedule whale shark tours from April 1 to 11, May 1 to 11, and May 31 to June 10 in 2026. However, we need to caution you about sighting history. Dates for 2027 are April 20 to 30, May 20 to 30, and June 18 to 28.

Recent Whale Shark Sighting History

Whale shark sightings at Gladden Spit have become increasingly unpredictable. Here’s what we’ve observed in recent years: During 2025, we had one whale shark sighting in April, and none in May or June. In 2024, we had no whale shark sightings at all. In April 2023, we spotted one whale shark, with no further sightings in May or June. In 2022, we ran one whale shark tour in April and two in May — we saw plenty of bull sharks but no whale sharks. In 2021, we ran three whale shark tours and saw a whale shark on one of them. During 2020, we did not run any whale shark tours due to COVID-19, although fishermen reported sightings at Gladden Spit. In 2019, for the first time, we had no whale shark sightings. In 2018, we saw whale sharks on fewer than half the days we went out.

TRIP PLAN

We run 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. Notably, this area features plenty of reef fish and healthy corals. Additionally, the lunch break offers an excellent opportunity for snorkeling just inside the barrier reef.

In accordance with Belizean sustainable tourism practices, the government allocates time slots for whale shark diving and snorkeling to tour operators. As a result, our departure time from Placencia depends on the assigned time slots. The travel time from Placencia to Gladden Spit is one hour and thirty minutes.

**Note:** the minimum age to enter the whale shark zone is 14.
