If I were to go back to French Polynesia again, I would not go to Bora Bora. I am glad I visited there once, but I was unimpressed. Yes, it was beautiful, but it was overused. The diving was no fun, because there were just too many people in one place. There were at least 5 dive boats and a submarine all in one location when we dove. Little kids, who were not even on the same dive boat as we were, were kicking me in the head to get a better look at things. The dive company had a videographer on the trip, who would not allow anyone close enough to the interesting stuff to take our own photos. Guess he wanted to sell up his.
I would be very skeptical of the map when it mentions Archeological Site, and you decide to drive yourself to these sites. There are NO signs from the road telling you where to stop, where to start looking for the site, and what you might find at these sites. In one situation we did pull over, found this under the road pathway, and then came to discover a pile of rocks behind a resort that did not really have any sort of marker. I guess you would pretend you were a zombie too if you wasted this much time trying to find sites that do not exist!
