An interesting alternative to the Celestun wildlife reserve visit is to Rio Lagartos. Northeast of Merida. It takes a much longer drive but it is absolutely worthwhile. As in many places in our beloved county, the name of the village is not accurate on may accounts; first, it is not a river (rio), there are non in the Yucatan peninsula, but a ria, which is sort of an estuary. Second there are no Lagartos (alligators), we have crocodiles (no need to translate). As in Celestún, you will be able to spot many bird, species (flamingoes included). The big plus are the salt flats at Las Coloradas (next to the salt company site); beautiful pink ponds making a dramatic contrast with the blue skies. Our recommendation: go see for yourselves !
