There are seven giant cannons on Bora Bora, perched on the hills above the four points of the island. U.S. servicemen stationed on the island during WWII installed them. Like the marae they can be difficult to find. Their general locations are the hills above Matira Point (about 6.5 km [4 mi] south of Vaitape); Fitiiu Point (on the east coast about 15 km [9 mi] from Vaitape via the southern route); and at Farepiti and Tereia Point (which are 2 km [1 mi] and 8 km [5 mi] north of Vaitape). The best way to see them, or some of them, is on an exciting but very bumpy 4WD tour.
