Great Adventures Reef & Green Island Cruises Reviews


Aslesha Belliappa

Great staff, great weather the day i visited, great experience overall. What blew me most was not the corals in the reef, but the warmth of the staff onboard the Great Adventures. A must visit to the reef through this trip organiser. A variety of activities offered- para sailing, snorkelling, diving & the reef walk. A day well spent


Karren Hill

Had an amazing time on green island. Great Adventures looked after all the tourists. It was a comfortable cruise across to the island and their package covering the snorkelling was great value. Would recommend them to visit the beautiful reef and marine animals. Had a wonderful time.
