All you needed was a nice pair of aqua shoes. Never saw anything in the water but little fishes. It's hardly a big swimming area because all the beaches right there are coarse dark sand and it's almost like a lake (being a small gulf)
they actually have a few light sand beaches which are probably artifically created w/trucked in sand. Your zipline wil prob be very crowded on wkend.
Great deal on bus transfers--what';s the link for that service please?
You will have such a goooooood time.
