You should head to the Tuamotus.
I must confess - this is the first climber's log I've signed for something I did below sea level!
I've been snorkeling in the Alboran Sea, the Aegean, and the Indian Ocean but this was even better than that.
What a beautiful place. Snorkeled till dusk and low tide. Second to last day of honeymoon.
Spent a funny afternoon being flushed in the toilet bowl. Also the witches brew was one of the sacry things I ever saw as a kid.
The only climb at this amazing location is the one back to the parking lot! :) Definitely worth checking out, but please be kind to the ecosystem. Oh, and bring a waterproof camera!
