Whale sharks

Whale sharks

A whale shark experience offers the opportunity to enter the water with one of the ocean’s largest animals during its seasonal presence along Tanzania’s coast. Qualified local guides use current sightings, sea conditions and responsible positioning to decide when and where the activity can take place. The aim is not to chase, touch or surround the animal. By keeping an appropriate distance and allowing the whale shark to move naturally, you can observe its size, movement and feeding behaviour without placing unnecessary pressure on it. With Lamai, the experience is included only where it can be arranged responsibly and fits naturally within the wider coastal journey.

Best for:

  • Travellers interested in marine wildlife
  • Confident swimmers
  • Nature photographers
  • Couples and private groups
  • Travellers combining safari with an active island stay

Where to experience

Mafia Island
Mafia Island is the main destination we associate with whale shark experiences in Tanzania. The island sits within a wider marine environment of reefs, mangroves, seagrass and coastal waters, making the ocean central to the character of the destination.
Waters surrounding Mafia Island marine park
The waters surrounding Mafia Island Marine Park form part of a diverse marine environment shaped by reefs, seagrass, mangroves and open coastal water. Whale shark excursions may explore these surrounding waters when seasonal feeding conditions bring the animals into the area.
Selected coastal areas during seasonal presence
Whale sharks may also appear in selected coastal waters around Mafia during their seasonal presence. Where an excursion takes place depends on where feeding activity is occurring and what local conditions allow that day.

When to go and what to bring

Whale sharks are present seasonally, while sightings, visibility and access are influenced by currents, wind, rainfall and natural food availability. Bring swimwear, a towel, sun protection and a rash vest or lightweight cover. Snorkelling equipment and required safety gear are normally provided by the local operator, although you may prefer to bring your own mask. Listen carefully to the guide’s instructions and avoid touching, following too closely or blocking the animal’s direction of travel.
