Caño Negro is the most important sizeable wetland in the country. This magnificent refuge is about 9,960 hectares (24,612 acres) and it
incorporates large lagoons, rivers, rainforest, open and semi-open environments, and the tiny village of the same name. Its climate has intense
influence from the dryer Northern Pacific region of Costa Rica and on a normal basis the dry season extends from December to April, sometimes even facing
the effects of severe droughts. Two very well defined seasons are responsible for drastic changes in the water levels, cold fronts and tropical depressions
can produce drenching rains on the foothills and lowlands, raising the level of the Río Frío (Cold River) up to 6 meters, subsequently flooding this vast
extension of land and triggering fish and plant reproduction.
The best time of the year to explore Caño Negro can be the dry season as more birds conglomerate around the remaining water mirrors, however the rainy season
or unexpected flash floods maximize the opportunities for exploration of the area and give access to incredible landscapes.
Caño Negro is a Ramsar Site, a wetland ecosystem denominated of international importance under the Ramsar Convention.
The Convention on Wetlands, known as the Ramsar Convention, is an intergovernmental environmental treaty established in 1971 by UNESCO,
today incorporating 169 nations, over 2,000 designated sites and encompassing 200,000,000 hectares (490,000,000 acres) of protected land.
The treaty supports for national action and involves international cooperation in regards of wetland conservation efforts, encouraging at
the same time thoughtful sustainable use of the site’s natural resources. Costa Rica, as part of the Convention on Wetlands, protects a total
of 569,742 hectares (1,407,860 acres).
What is a wetland?
The fundamental factor that characterizes a wetland from other land form or water body is the particular plant composition dominated by
specific aquatic plants, all adapted to the particular hydric soil. These permanent or seasonal aquatic ecosystems play important roles in water
purification, flood control, shoreline stability, and carbon sequestration. Wetlands are within the most biologically diverse ecosystems in the planet,
serving as sanctuaries of a wide variety of animals and particular plant life.
A lot of day tours are offered to explore the Caño Negro Wetlands, particularly from the Arenal Volcano area, however this operations will only take
you into Los Chiles or a nearby location and navigate and watch some wildlife along the Río Frío (Cold River), and not into the actual refuge. When we visit
this area we take you into the actual refuge and stay in Caño Negro Natural Lodge right in the village of Caño Negro. Our boat trips are private and flexible,
so we truly explore the area.
Exploration of the Wetland and special birds
Several lagoons and the Río Frío Canal can be explored by boat, with certain differences in where we can access depending on water levels.
Almost any level of water you can find in Caño Negro is good to have a great experience, some low levels favor conglomeration of birds because of
the abundance of food, and some higher levels allow access to wonderful lagoons where birds are sparse throughout a vast extension, but you get to
experience more of the landscapes. Boat trips can take place early in the morning a couple of hours before breakfast, mid morning, or mid to late afternoon,
we program the boat adventures based of species requirements, weather conditions, and water levels, your guide will help you coordinate and plan properly.
