More ways to explore the area's outdoor wonders
You step off the vehicle into humid air threaded with the sour edge of mineral-rich steam; the trail slips immediately into shade, roots and volcanic rock underfoot. The path negotiates old lava fields rewilding into scrub and young trees, and every clearing frames Arenal’s conical silhouette with Lake Arenal glinting below. Guides point out hardened pahoehoe and ʻaʻā textures as if reading the volcano’s ledger.

Reserve your spot on the Arenal Volcano Hike To The Lava Flows today and enjoy a trusted, highly rated experience designed to help you make the most of your adventure.
Bring enough water
Carry at least 1 L of water per person—humidity and volcanic rock can sap energy faster than flat trails.
Sturdy footwear only
Traction matters: closed-toe hiking shoes with grippy soles help on loose volcanic rock and root-strewn rainforest soil.
Expect mud in the wet season
Rain can turn paths slick; consider gaiters and trekking poles if visiting May–November.
Stay on the trail
Hardened lava and recovering vegetation are fragile—follow your guide to avoid damaging regrowth and for your safety.
Sturdy hiking shoes
Good traction and ankle support for uneven volcanic rock and muddy rainforest paths.
Light rain jacket
