Imagine the scene. Just you and the warm Indian Ocean waters off Tofo beach. Along with the giants of the deep.

Tofo is one of the few places in the world where it is possible to snorkel with Earth’s largest living fish – the increasingly-threatened whale shark. Growing to an astonishing 14m in length, their slow peaceful movements are matched by the elegant motion of manta rays, whose wingspans can stretch seven metres.

This is a private tour and the captain runs counter to any group tours, ensuring there is nobody else in the water but the mantas and whale sharks.
