(1.916 m.a.s.l.) It`s in Guanacaste province. It`s the easternmost volcan of Cordillera Guanacaste.

It consists of four volcanic peaks and two twin-craters (sometimes called as separate volcan of Montezuma). It`s covered with savannah, rain forest at midelevation and above by clouds forests. From the western slope of Tenorio flows down the Tenorio river and from the southern slope rivers Tenorito and Martirio. From its top spreads the sight for Guatuso and San Carlos lowlands, Lake Nicaragua, Cano Negro National Reserve and Arenal Lake. From its slopes snakes down the Rio Frio. A legend exists of an eruption in 1816, but the volcano was observed to be densely forested in 1864 and is not considered to have erupted in historical time. Since 1989 it has been under a pre-feasibility study to determine its geothermal potential. In 1998 the vicinity of the volcano was hit by the 1 R scale earthquake.

Since 1995 the volcan is within Volcan Tenorio National Park. It`s known among others for the hot springs (with the temperatures up to 94 C) and bumbling holes. At the foot of Tenorio spread the plantations of macadamia.
