The Raphia palms that line the banks of the Frío River drop fruit that turn the water black, giving the wetlands its name: Caño Negro. Spanning 25,000 acres of forests, marshes, rivers and grasslands in Northern Costa Rica, Caño Negro is one of the world’s most important wetlands.
Designated an international conservation site by the Ramsar Convention on wetlands, Caño Negro protects endangered species like the bright pink roseate spoon bill and the jacana, which only nest two places in Costa Rica; rarely seen nocturnal hunters like the jaguar and maragay; and even endangered fish like the alligator gar, which gets its name from its odd appearance and dual rows of teeth.
Floating down the Frío River in canoe or pontoon boat, guests have the opportunity to see howler monkeys, king fishers, green basilisk lizards, caimans, and many other species. Along the way, naturalist guides scout for wildlife and explain the many oddities of Caño Negro’s animals and habitats.
