Took bus to the river to a kayaking excursion. Tour guides are very good, the river is gorgeous. The food was a buffet style and pretty good. Bring bug spray, otherwise they will talk you into buying theirs.
This port is gorgeous and plenty to do. We did the Express Zip Line and it was absolutely perfect for us. It left us time to get to the beach. There is not need to get a cab, the beach is very pretty right there. Very clean and safe.
