... in memory of a beautiful day with many experience.
After a funny and exciting jeep ride to some hotspots on this island with our friendly tourguide Mahina - the marquesian word for white moon - we decided to place a geocache nearby the harbor. So you can get it while staying in port.
Update 5.6.2016: We heard, the restaurant has closed now. But obviously you can still meet very friendly people there. Look at some last logs. Ask them about Thomas Mahina, the former restaurant owner (our friend White Moon). And we are sure, you can go to the "ground zero". ... and bear in mind that without this one there is no cache for cruisers current state. 
Originally Listing: The cache is located outside a small restaurant under terrace floor. The owner is in the know about the cache and looks after it. If you have trouble to find it, ask in the restaurant for Thomas Mahina, he is the owner and will help you. And by the way... he can help you too to go to the other cache on the hill (TEKEIKA)!
Happy hunting & have fun
