The Experience

You step into humid forest where leaves ping with dripping water and the volcano looms like a patient giant. Narrow trails thread through buttressed trees and vines; the path climbs over jagged black lava, the rock still holding the shape of old flows. Arenal’s cone fills the skyline, silent now but impossible to ignore.

Before You Go

Wear grippy hiking shoes

Lava rock and muddy jungle stretches demand good traction—no sandals or slick soles.

Bring a swim change

A freshwater lake and hot springs are on the itinerary—pack a quick-dry towel and swimsuit.

Start early to avoid heat

Morning departure reduces mid-day heat and increases chances of clearer views.

Protect electronics

Bring a small dry bag—rain, spray and damp jungle can damage cameras and phones.

Conservation Note

Stay on marked trails, respect thermal-resort rules and avoid disturbing wildlife; local guides help minimize impact by directing foot traffic and sharing leave-no-trace practices.

Arenal’s 1968 eruption reshaped local communities and lava fields visible today; the park area preserves both geological features and local stories tied to that event.
