I enjoyed Rio Tampaon a lot, for me it had the added edge of going with one friend and scouting most drops, i.e. a bit of an expedition feel
Beautiful water, and incredible huecos (swiss cheese holes in the rock) all around it. Even though it wasn't challenging paddling, it was so beautiful that I'd love to go back there.
