The Northern Highlands
By northern highlands, we refer to the mountain ranges of Guanacaste and Tilarán.
They are separated by the Arenal reservoir and the subsequent lowland, which extends up to the "Lago de Nicaragua”.
The Cordillera de Tilarán forms the watershed between the Atlantic and Pacific. The best known attraction in the region is the active Volcán Arenal, the most currently active volcano in Central America, which came into action in July 2009. Directly next to the Arenal volcano you can find a reservoir that is used to produce energy. The Arenal Lake is internationally recognized as one of the best windsurfing areas. Less known, but more exciting, is the cloud forest region around Monteverde. Monteverde is a nature reserve that offers many different hiking trails through a beautiful nature. We can see here countless trees and plant species; the diversity of fauna is unsurpassed. Close to Monteverde is the town Santa Elena, a very interesting place as a starting point for exploring nature.
Even less is known is the Tenorio Volcano, which is extinguished since long time ago, and you can do excellent hiking in its origins. The Rio Celeste is a sky blue-colored river that originates at the Tenorio Volcano. You can experience with our tours how the water gets its blue-sky color. Just a few miles west of the Rio Celeste, you follow straight line to get into the wetlands of Caño Negro and the Río Frío. This is the most important wetland in Costa Rica, and it is of course protected. The Wildlife in the area is unsurpassed.
The Rio Frio opens into the Rio San Juan in Nicaragua. The Rio San Ramon also does, and you can take beautiful boat trips to Nicaragua. Animal watching tours available in the foreground.
