Orosí Volcano, Extinct volcano in Guanacaste National Park, Costa Rica
Orosí Volcano is an extinct volcano in northern Costa Rica, close to the Nicaraguan border, and part of the Guanacaste mountain range. It falls within Guanacaste National Park, a protected area covering a range of forest types across different elevations.
The volcano last erupted around 3,500 years ago, an event that shaped much of the landscape visible today in northern Guanacaste. Reports from the 19th century hinted at possible renewed activity, but these accounts were never confirmed.
The volcano sits within a national park where the land is left largely untouched, and visitors feel this as soon as they step onto the trails. The sounds of birds and the density of the forest give the area a character that is hard to find closer to the coast.
The hiking trails inside the national park offer routes of varying difficulty leading toward the upper slopes of the volcano. Conditions change fast at this elevation, so bringing layers and enough water is a good idea regardless of how the day starts.
The slopes sit at a point where animals from coastal forests and highland areas cross paths, which means a single hike can bring sightings from two very different worlds. This overlap is not always obvious from a map, but it becomes clear the moment you start watching the tree line.
