The Hakone caldera Owakudani (大湧谷) was named the “Valley of Hell” by locals for volcanic sulphur gasses that rise up from underneath. Nonetheless, Owakudani offers a truly unique landscape with stunning views over Hakone from the rope way that reaches the caldera’s highest point. Let’s be honest, if you were to say “I walked across the Valley of Hell,” that would leave quite an impression, wouldn’t it?
Owakudani caldera was formed by the last Mount Hakone eruption, about 3,000 years ago. Since last year the area has become active again so public access has been restricted for the time being. Please check Hakone Portal’s website for the latest information on the situation.
