Trailhead choice to Mt. Shiga affects the feel and duration. The last 600m to the summit is a steep scree slope. This is a very exposed and challenging trail. Be well prepared for sunshine, wind, and longer hike time at altitude. You can hike this trail from either way.
There’s a shelter at the top of Mt. Iwasuge that has a hut nearby for use of a take home toilet system.

*Mountain climbing registration is required. Check this page for details.
