The name Jigokudani, meaning "Hell's Valley", is due to the steam and boiling water that bubbles out of small crevices in the frozen ground, surrounded by steep cliffs and formidably cold and hostile forests.The heavy snowfalls (snow covers the ground for 4 months a year), an elevation of 850 metres, and being only accessible via a narrow two kilometre footpath through the forest, keep it uncrowded despite being relatively well-known.
