Mangaia: See
== Do ==
There is not much to do on Mangaia, except walking around, having a coconut, talk to the friendly locals and go fishing.
Fishing inside or outside the reef is very rewarding, and there is no ciguatera here unlike in Rarotonga. Spearfishing outside the reef is possible as well.
There are some very nice secluded beaches, but the reef is to shallow for swimming. With a little common sense it is, however safe to swim and snorkel outside the reef when the sea is calm.
Mangaia is also good for walking.
