Arenal woke up violently in 1968 and spent the next four decades throwing glowing rock down its slopes — the nightly lava show that put La Fortuna on the world map. Since 2010 the volcano has been in a resting phase, steaming quietly above rainforest and Lake Arenal, but the silhouette lost none of its drama: a near-perfect cone rising 1,670 meters straight out of green.
Today Arenal anchors Costa Rica's adventure capital. You hike the 1968 lava fields where forest is slowly winning the rock back, cross hanging bridges at canopy height with the cone filling the sky, and end the day in hot springs heated by the volcano's own geothermal core. Climbing to the crater is prohibited — this is a mountain you experience from all around, not from the top.

Good to know
Best season
February–April gives the best odds of a cloud-free cone; it's worth visiting year-round — mornings are clearest.
Difficulty & access
Easy to moderate — flat lava-field loops and hanging-bridge walks around the base; the summit itself is closed. About 3 hours from San José, base town La Fortuna.
Insider tip
The classic postcard angle is from the lake side, toward El Castillo. Save the hot springs for after dark, when the air cools and the pools feel earned.
