Before the volcano’s active period in 1968, a lavish canopy of vegetation covered the Arenal Volcano. People that climbed Arenal’s summit related that inside the crater there were big trees and some heat due to small steam outlets. Nowadays, the green area is located on the east side of the Mountain, and other little green parts can be seen on the north and south sides of the volcano.
Enjoy the most extraordinary view of the Arenal Volcano on a gentle hike along the base of this marvelous “Mountain of Fire”. The hike begins on the south west side of the volcano, at Los Tucanes Trail. This trail will take you through the forest over recent lava flows, and an important area that was destroyed in 1968, which is now in process of regeneration. This hike takes about 2 ½ hours
