We would recommend that you go to the Tahaa motu that was our most relaxing day of the trip you can snokel but we didn't see much but we just hung out on the beach and drank the wonderful drinks served out of coconuts and had a wonderful lunch right there on the motu. We did the ray & shark excursion and had a good time also did the jeep tour on ratea(sp?) had a great time but it was alittle bumpy.
Hope this helps a little.
