Carry water and light snacks
Bring 1–2 liters of water and compact snacks—there are no reliable supplies on the trail and the ascent is dry and energy-draining.
Use the supplied gas mask but bring your own fit test
Masks are typically provided, but fit can vary—test yours before descending into sulfur fumes and keep breathing shallow near vents.
Wear sturdy, grippy footwear
Expect loose volcanic scree and steep sections—ankle-supporting hiking boots improve traction and confidence on the climb and descent.
Plan for very early start and cold
Temperatures at the rim are several degrees colder than the coast—bring warm layers and a charged headlamp; tours start around midnight.
Headlamp with fresh batteries
Critical for the night ascent and hands-free navigation on rocky trail sections.
Gas mask or filter (N95/cloth provided by guide)
Protects against sulfur fumes near vents; guides usually supply masks but personal fit helps.
Sturdy hiking boots
Support and grip on loose volcanic scree reduce risk of slips on steep sections.
Insulating layers and wind/rain shell
Night and rim temperatures are cold and wind-exposed; a shell keeps you dry in rain or mist.
