We decided to try one of the ATV Moorea tours and are so glad we did! The tour was absolutely fantastic: we got to drive on both paved roads and in the mud all around the island, swing from banyan trees, see amazing vistas, and eat delicious ice cream. The guide was great and emailed us photos from the excursion a few days later. We highly recommend this tour, and be sure to upgrade to the extended route because the view at the end from Magic Mountain is the best part!
We did an off-road tour in a dune buggy and it was a lot of fun. We kind of “crashed” on one of the big jumps, but fortunately did not get hurt too bad. There was also a jump into the Jade Cavern cenote partway through the excursion. As you can probably tell from the video, the dune buggy ride is very, very bumpy.
