The hike begins in near-dark, headlamps bobbing as a narrow road climbs out of sugarcane flats toward the volcanic highlands. Damp air tightens around your pack; sulfur stings the nostrils and a wan, turquoise lake waits below a jagged rim. At the crater edge, blue tongues of flame curl from fumaroles—an otherworldly show that only appears where sulfuric gas ignites.

Start before midnight
Pick-up and ferry timings are early—arrive rested and use the provided transfers to avoid navigating the route at night alone.

Temperatures can drop sharply at altitude—pack a warm layer and keep moving to stay warm during the observation window.
Headlamp with fresh batteries
Hands-free light for pre-dawn hiking and navigating rocky trails.

Respirator or gas mask
Filters sulfur fumes around fumaroles—often provided but comfortable to carry your own.
