Mt. Senjozan with an altitude of 600 m is a part of Daisen-Oki National Park. It is a popular scenic spot, where people can easily enjoy hiking, viewing landscapes and questing for historic sites. The mountain was worshipped as the sacred place for Shugendo (mountain practice) in the Heian period (794-1192). It is also known as the place where Emperor Go-Daigo hid himself after he had escaped from Oki Island in the late Kamakura Period (1192-1336).

The 600 m wide rocky cliff called Byobu-Iwa (Folding Screen Rock) extends along the eastern side of the mountain, beside which a waterfall flows down. There are many temples and shrines of Shugendo and historic sites in the mountain, which create distinctive atmosphere. The mountain is crowded with viewers of autumn leaves in November. Double-flowered cherry trees are in full bloom in spring in Manbon-zakura (10,000 Cherry Tress) Park at the foot of the mountain.
