The main highlights of this Xtreme adventure, making it totally unique, are the high speed Miami Vice style run, through the amazing islands of the north sound with its myriad coral reefs, the Stingray City Marine Park swim where we can have our picture taken actually holding one of these ancient and beautiful fish; the Robinson Crusoe style, buffet lunch at Green Island with your toes in the water; the tour of Nelson's Dockyard with your own on-board local historian; the guided snorkel trip at the awesome Pillars of Hercules with its volcanic boulders below the surface, and the swim and beach combing at the extremely secluded and beautiful Rendezvous Bay.
