Bessan (別山, Bessan) is located on the border of Gujō, Gifu Prefecture, and Hakusan, Ishikawa Prefecture, Japan, and rises to a height of 2,399 m (7,871 ft).

Mount Haku has been climbed for religious purposes for centuries.

Near the lake are the ruins for the Bessan Room (別山室 Bessan-ya), which was used as a rest house for those making the pilgrimage up the mountain.

Near the peak of the mountain is the tree line made up of Siberian Dwarf Pines.

A wider variety of plants can be seen at lower levels, but the surrounding area is part of Japan's snow country, so it is covered by snow for more than half of the year.
