Do not book this tour in advance even tho it only runs 3 days a week and may sell out. Book the day before so you know what the weather conditions will be like. If there is a storm the day before, know that visibility will be GREATLY reduced due to the currents disturbing the coral reef ocean floor. The sail out to the reef was an extremely cold and choppy ride. Many were not prepared and were freezing.

If you are a weak swimmer or have never snorkeled before, only go if the conditions are excellent. Only 25 of the passengers went snorkeling due to the literally 10 to 15 foot waves around the boat at the snorkel site. All of them returned to the boat within 10 minutes due to the high waves and lack of visibility.

Also the kayaking was pretty lame. You only paddle along the coast of the mangrove, not very far from the boat, less than 5 minute continuous paddle. In fact, the kayak guide just sends you back on your own to the boat and waits for the next group to paddle out to her - that's how close it is.
