Arenal Volcano: Complete Visitor Guide

Travel GuideBy Carlos Rodríguez · Founder & Lead Guide, Fortuna ExpeditionsPublished July 22, 2026· Updated July 23, 2026

Arenal Volcano is Costa Rica's most famous volcano — a near-perfect cone above La Fortuna. It's currently in a resting phase (no lava since 2010), but the national park's lava-field trails, wildlife and views make it a must-do.

Here's how to visit: the best hikes, viewpoints, timing and tours.

Is Arenal Volcano Active?

Arenal is considered active but currently at rest — no visible eruptions since 2010. You won't see glowing lava, but you can safely hike the hardened 1968 flow right at its base.

Best Hikes

The Arenal Volcano Hike ($78) covers the 1968 lava trail and forest paths. For canopy views, add the hanging bridges, or see it from the water on the lake tour.

Best Viewpoints

The park's Mirador, the shore of Lake Arenal, and many hotel decks around El Castillo offer classic cone views. Mornings are clearest — the summit often clouds over by afternoon.

When to Go

Dry season (Dec-Apr) has the clearest skies, but green season (May-Nov) is lush and quieter. See our best time to visit Costa Rica guide.
