Volcano walk
Walk on a natural rock trail made from lava flow.

We are temporarily closed from 11th April to 31th May.

The picturesque scenery of ‘Onioshidashi’ is a rare rock formation made by lava flows from an eruption in 1783.
There are five courses, that take from around 25 minutes to 80 minutes. Choose the one that best suits your interests or your physical condition.

You will be able to see many beautiful alpine plants such as ‘Iwakagami’, ’Hakusan-shakunage’, and ’Tugazakura’ blooming between rugged rocks, as well as wild birds such as ‘Hojiro’ and butterflies including ‘Benihikage’. Enjoy the trails through the wild nature of the Asama area.
We have many wonderful views thanks to the location. It is possible to see mountains including Kusatsu Shirane, the Northern Alps, and the Tanigawa mountain range.

Feel free to use our nature guide service, provided by volunteer Asama supporters (reservation needed, free of charge), for the opportunity to learn more about the nature of the Asama area.
