Our family wanted to do a dolphin tour and we were so glad we chose One HHI. It was great being on a smaller pontoon boat instead of a larger boat with lots of people. We were able to see many dolphins which swam fairly close by to the boat. Since it was a pontoon boat, we were able to go from side to side of the boat as the dolphins swam around us. The captain and tour guide gave lots of good information about the island itself and about dolphins. Great experience!
