If museums are on your list of things to see in Nuku Hiva, then you might want to head to Musée Enana. If you want to experience more of the culture Nuku Hiva has to offer, head to Notre Dame Cathedral of the Marquesas, Monument to the Dead, and Pae Pae Piki Vehine.
Monument to the Dead is just one of the landmarks located 0.4 mi (0.6 km) from central Taiohae, so you might want to stop by for a few pics during your trip.
