Climb to the crater rim of Mt. Usu, peer into recent volcanic scars, then descend to Lake Toya for geological context at the Toya-Usu Geopark. This small-group day tour pairs a hands-on volcano hike with lake viewpoints and on-site interpretation.
More ways to explore the area's outdoor wonders
A cool wind from the crater rim cuts across the trail as you climb—pines crackle on the slope and the crater breathes faint steam. Below, Lake Toya opens in a wide, blue bowl with a black volcanic shoreline; boats are small dots, and the island in the center holds ancient forest. The day begins with a short drive to the trailhead, then a steady ascent through mixed forest to the crater rim where the raw geometry of recent eruptions is visible.

Layer for wind and sun
The crater rim is exposed and can be much windier and colder than the trailhead—pack a wind shell and sun protection.
Footwear matters
Choose trail shoes with good grip; the upper approach has loose volcanic scree and steeper pitches.
Hydrate and snack
Carry at least 1–1.5 L of water and a light lunch or snacks—the tour includes a sandwich but you’ll want quick energy on the ascent.
Respect geothermal areas
Follow guide directions and signage—warm ground and fumaroles can be unstable and dangerous.
Sturdy trail shoes
Grip and ankle support help on loose volcanic scree and steep sections.
Windproof jacket
Crater rims are exposed and can be chillier than lower elevations.
spring
Sun protection (hat, sunscreen)
Open viewpoints get intense sun reflected off the lake and dark volcanic rock.
summer
Daypack with water and snacks
Carry at least 1–1.5 L of water, layers, and a camera for viewpoints.
