Cañón de Somoto is located in the northwest of the country, near the border with Honduras. The canyon is 160 meters deep, about 3 kilometers long, formed by the river Coco about 8 million years ago, and today it is under state protection as a national natural monument. The Coco River is formed by merging the Tapacalí and Comali rivers. The usual tour includes hiking, swimming on small rapids, and enjoying the beautiful views of untouched nature. Guidance is mandatory, but the prices are very reasonable.
