Rio Grande de Tarcoles: "The Bridge of the Crocodiles"
Known also as Tarcoles, it is formed by the confluence of the water courses of the Virilla and the Grande River of San Ramón. The Greater Tarcoles, is one of the most extensive rivers of the country.
The river forms part of the habitat for the American Crocodile! The rivera at its mouth is home to numerous ducks and shorebirds. Among the many resident herons are boat billed and tiger heron. Other birds that can be observed are the caraway, the mangrove canary and the dwarf kingfisher.
Known for its abundance of American crocodiles, the Tarcoles River is said to have one of the largest populations in the world! Twenty five crocodiles per square kilometer! Often these large reptiles can be seen swimming by the river or sunbathing along the sandbanks or sediments. Other reptiles that live in the river are: caymans, cherepo and great iguanas. In addition, the river also hosts more than 50 species of migratory birds, native and coastal species, including a variety of herons, pink spatula, red and green barnacles. The flocks of red lapa parrots fly two by two from the bridge over the river to the mangrove where much of the population of the area usually sleep and seek their food.
This region is very popular with both domestic and foreign tourists, because of the large number of crocodiles and lizards that inhabit it and can be seen on the banks of the river.
