Bora Bora with Maupiti
There are three popular ways to explore Bora Bora: by boat on the lagoon, by 4WD into the interior exploring the hills, and by driving around the 32-km (20-mi) main island road.
While it's very popular to drive around on one's own, if you have limited time it might be better to book an organized Circle Island tour. There are several marae (ancient Polynesian temples) and seven remaining WWII guns tucked away in the jungle interior, which are best pointed out by the experts.
If you want to cycle, it takes a good four hours to circle the island.
