We booked the Chacchoben Extreme. We had to leave the port to meet our group, but it was a very short walk. A small air conditioned van, water, and a very knowledgeable guide made the hour drive very enjoyable. The ruins were explained to us in detail by our guide (David). He was extremely knowledgeable and came across as a quality person. His passion for his country and his positive attitude was very much appreciated. Once we left the ruins we then headed to Bacalar Lagoon. Had an awesome lunch provided on the proprierty of the resort and then kayaked and lounged out for a couple of hours. Not a great swimming area (too many rocks), but a very pristine area. Our guide David was awesome.
