Snorkel with the gentle giants of Donsal. 

If you’re not a scuba diver, don’t despair! You can still enjoy the thrill of seeing the awesome and harmless whale sharks with no more than a mask and snorkel. These amazing giants are the world’s largest fish growing up to 12 metres long and weighing up to 20 tonnes and can only usually be seen on a dive, but in Donsal these unbelievable creatures swim right up to the surface.
