Guided boattour for about 2 hours in this Unesco natural park. Boatrental, entrance to the park and English/Spanish speaking guide are included. You´ll see birds, different types of mangroves, most probably crocodiles. As for the Flamingos: this park is where their nesting aerea is (we´re not allowed to go to the nests), so you´ll definitely see them the whole year round. How many? There are days we see only ten or a hundred, but you´ll never see a thousand ;-).
