Known for offering exceptional bird watching and mountain trekking opportunities, Valle Nuevo National Park is one of Constanza’s crown jewels. Past the exit to the Aguas Blancas waterfall, the road climbs toward a mountaintop mesa at an altitude of more than 2,200 meters (7,200 feet), surrounding you with tall pine and green ebony trees. This protected area, known as “Madre de las Aguas” or the mother of water sources, boasts multiple rivers that supply the country, with temperatures hovering between 14°C (57°F) and 22°C (71°F). In December, they can drop to below zero, with frost and even ice on occasion. Valle Nuevo’s biodiversity is astounding: stretching 902 square kilometers (348 square miles), the park encompasses cloud forest, highland plains, and vast savannas of alpine grass hugged by rocky mountains, home to over 500 species of plants, of which 138 are endemic to Valle Nuevo, as well as numerous species of amphibians, reptiles, butterflies, and birds. It’s the sort of cold, remote, and lush mountainous landscape you won’t see anywhere else in the country, with a myriad of opportunities to commune in nature–hiking, horseback riding or biking around criollo pines, and near mist-covered peaks. Tucked deep amid this scenery is an eco-lodge, the only one located within the limits of Valle Nuevo National Park.
