Arenal Volcano National Park protects 12,124 hectares of unique volcanic ecosystems, offering the opportunity to explore one of the most studied and photographed volcanoes in the world. The park’s trails traverse different life zones, from humid tropical forest to cloud forest, each with distinctive ecological characteristics.
The main trail, Sendero Las Coladas, leads through historic lava flows where visitors can directly observe the effects of volcanic activity and ecological succession processes. Guides specialized in volcanology explain the formation of the volcanic cone, the types of eruptions, and the influence of volcanism on regional biodiversity.

During the hike, participants have exceptional opportunities to observe wildlife adapted to volcanic environments, including endemic species that have evolved in response to the unique conditions of the volcanic ecosystem. The park is home to more than 850 species of birds, including the resplendent quetzal, and mammals such as jaguars, pumas, and tapirs.
Strategically placed viewpoints offer panoramic views of the volcanic cone, Lake Arenal, and the Tilarán Mountain Range. On clear days, it is possible to observe the summit of the volcano and occasionally steam emissions from the active crater. The experience includes education on volcanic monitoring, early warning systems and coexistence with active volcanoes.
