From the Mount Iwasuge trailhead in Shiga Kogen, this return climbs through old-growth forest to the ridge, passes the 2,295 m Mount Iwasuge with its shelter, and follows the crest to Ura-Iwasuge, at 2,341 m the highest peak of Shiga Kogen. The open ridge between the two summits is a fine viewpoint, and alpine flowers such as rhododendron and alpine pinks bloom in summer.
