I'm not a horse back rider, but this was a very cool experience. We "walked" to the beach and then let the horse run a little along the beach. A little scarry for a first timer but exhilirating. Our guide stopped, scaled a coconut tree and brought down a couple coconuts to drink. I'd strongly suggest doing this.
