Mt. Sanbe-san is the generic name of seven mountains, the highest of which is Mt. Osanbe, 1,126 meters above sea level. It is a scenic spot representing the Iwami district in the central part of Shimane Prefecture. The appearance is graceful, and the group of these volcanoes with the vast extent of their mountain bases belongs to Daisen-Oki National Park.

In the Mt. Sanbe-san area, there are grassy plains at the feet of the mountains, forests of beeches and mizunara (a kind of beech tree) on the sides, and a crater lake on the top, all of which provide you with a wealth of various remaining types of nature. On the vast grassy plains spreading out over Nishi-no-hara and Higashi-no-hara at the foot of the mountain, cattle are left to graze, dead grass is burnt in spring, and picnics and hiking are enjoyed in summer. At Lake Himeno-ga-ike in Kita-no-hara, tens of thousands of irises are in full bloom in early summer.

Hot springs dot the area nearby. Some of these are: Sanbe-onsen Hot Spring famous for being promoting longevity, Yugakae-onsen, Koyahara-onsen, and Ikeda Radium-onsen where only a single inn is available. Inns at all these hot springs are suitable base camps for climbing Mt. Sanbe-san.
