Frequently Asked Questions

Is it safe to swim with whale sharks?

Absolutely. Despite their intimidating size, whale sharks are known as the "Gentle Giants" of the sea. They are filter feeders that subsist entirely on plankton, krill, and small fish. They have no interest in humans and are famously docile, allowing for a peaceful and awe-inspiring shared swimming experience.

When is the best time to see whale sharks in Tanzania?

The peak season for sightings—particularly around Mafia Island—is from October to March. During these months, the nutrient-rich waters draw large numbers of whale sharks close to the surface to feed, making them very easy to locate.

Do I need professional diving experience?

No. Because whale sharks typically feed near the surface, snorkeling is the primary way to interact with them. You do not need SCUBA certification or deep-diving experience. A mask, snorkel, and fins are all you need to witness these magnificent creatures from just a few meters away.

How long does the activity typically last?

Most whale shark excursions are half-day tours, lasting between 3 and 5 hours. The exact duration depends on how quickly the scouts locate a pod and how long the sharks remain stationary enough for swimmers to enter the water.

What essential items should I bring?

To stay comfortable, you should pack: Swimwear & Rash Guard: A rash guard provides extra sun protection while you are on the surface. Biodegradable Sunscreen: To protect the delicate marine ecosystem. Towel & Dry Clothes: For the boat ride back to shore. Waterproof Camera: A GoPro or similar action camera is highly recommended for capturing high-definition underwater footage.
