Frequently Asked Questions

Can you swim with sperm whales in Mauritius?

No. Swimming, snorkeling and diving with whales have been prohibited in Mauritius since 2020. Whale trips are boat based observation only, although swimming with dolphins is still allowed.

When is the best time to go?

Sperm whales are resident year-round. The calmest, most reliable window is roughly September to April, while humpback whales pass July to November.

Where do the tours go?

Off the west coast between Tamarin, Black River (Riviere Noire) and Le Morne, where the ocean floor drops sharply just beyond the reef.

How do the trips work?

Early-morning boat excursions with local operators, since sperm whales are usually found in the calm morning sea close to the drop-off.
