This was the second time we have done the Dolphin Discoveries dolphin excursion. Our captain, Daniel, was terrific--funny, informative. We had great luck in finding dolphins to observe while in the water, and our time at swimming by the Captain Cook Monument provided such clear viewings of fish and coral. Amazingly, we concluded our tour by luckily seeing many spinner dolphins jumping and swimming by our boat--too many dolphins to count, in fact. A great experience, and I we do the manta ray dive in future, we will also book through them. Small boat tours, big time experience.
