Excellent for nature lovers. A close-up of the flamingos is amazing, beautiful. Overall it is well worth going to relax, walk in the mangroves, swim in the water hole and after the tour (1 hour approx.) throw yourself on a sunlounger on the beach or sample the local cuisine. I highly recommend Merida, it is just 1hr away and fairly easy to get to. I would suggest avoiding going in the afternoon asit will be difficult to find other visitors to split the cost of the tour boat (between $ 700 and $ 1,000).
