Morning wind cuts across the caldera as the trail opens onto a rim that feels more like a living room for the island — broad, raw, and quietly hot where steam sighs through fumaroles. The walk begins with low, grassy tundra and moves onto packed volcanic ash and hardened lava flows; the crater yawns beside you, a shallow bowl punctured by fumaroles that still warm the air.

Start at dawn
Morning air is cooler and visibility is better for views into the caldera; bus to the trailhead leaves early from Puerto Villamil.
Bring layers
Wind from the ocean can be chilly on the rim even after a sunny start — pack a windbreaker and a warm mid-layer.
Footwear matters
Sturdy hiking shoes with good grip help on loose volcanic ash and jagged lava edges near Chico.
Hydration and lunch
Carry at least 1–2 liters of water and the provided box lunch; there are no services on the trail.
Sturdy hiking shoes
Support and traction for loose ash, hardened lava and uneven trail surfaces.
Windbreaker or warm mid-layer
Protects against sharp caldera winds and cooling temperatures at higher exposure.
Sun protection (hat, sunscreen, sunglasses)
Strong equatorial sun and reflection off light volcanic ground increase UV exposure.
summer
1–2 liters of water and small snacks
Hydration is crucial on the exposed stretches; park rest stops are limited.
