More ways to explore the area's outdoor wonders
A crisp wind carries the sulfurous breath of Usuzan as you step from the forest into the open scars of recent eruptions. Early sunlight picks out steam rising from fumaroles like small ghosts along the crater rim, while the Pacific glints beyond and Lake Toya opens to the north. The trail shifts between mossy trunks and volcanic scree; every turn brings a different angle on the crater’s raw geometry.

History
Usuzan’s recent eruptions (notably in the late 1970s and 2000) dramatically altered local topography and led to scientific monitoring and improved community evacuation planning.
Conservation
The volcanic landscape regenerates slowly; stick to trails, pack out all waste, and avoid collecting rocks or disturbing fumaroles to protect fragile habitats.

Respect fumarole zones
Stay on marked trails and heed your guide — ground and gases near vents can be unstable and irritating to the lungs.
Footwear and poles
Wear grippy hiking boots and use poles for stability on loose volcanic scree and steep forest sections.
Carry adequate water
Bring at least 1.5–2 liters; there are no reliable water sources on the ascent and exertion can spike quickly on steep sections.
Watch the weather window
Visibility and wind change fast—plan the hike mid‑morning to early afternoon when conditions are most stable.
Sturdy hiking boots
Provides traction on wet roots and loose volcanic scree.
Lightweight waterproof layer
Wind and sudden rain are common near the summit; a breathable shell keeps you comfortable.
Hiking poles
Helpful for balance on steep or loose sections and reduces knee strain on descent.
Water bottle or hydration bladder (2L)
No water refills en route; carry enough to stay hydrated through the climb and return.
