Route Guide

Route Guide
Renge Onsen is known as a hot spring discovered by Kenshin Uesugi. It is popular for its wild outdoor spa. A trailhead starts from Renge Onsen Lodge. The beginning of the trail is almost flat. Tenguno-niwa is reached after a deep forest zone. Pinguicula and Hakusan-shajin can be seen along the trail. Larches spread their branches horizontally. There is a great view of Mt. Yukikura-dake and Mt. Asahi-dake in sight.
From this point, the elevation gradually increases. Take a short break while standing as needed. After a climb on the straight trail not covered by trees anymore, Hakuba 0ike Mountain hut is reached. There is a camping site in front of the hut. The Alpine plants at the site are beautiful.

Mountains in front of Hakuba Oike Mountain hut lead to Mt. Shirouma-dake. Start hiking on the ridgeline known as Raicho slope, where ptarmigan can be spotted occasionally. Take a short break while standing at Funakoshi-no-atama. Continue onto the graveled trail to Mt. Korenge-san. Your view becomes wider as the elevation becomes higher.

Passing the summit of Mt. Korenge-san where an iron sword is plunged into the ground, Mt. Shirouma-dake appears in your direction. Take a right trail at Mikuni-zakai. This path leads to Mt. Asahi-dake. This trail eventually goes to Oyashirazu in Niigata along the Japan sea. This is a difficult path to follow. It will take one hour from Mikuni-zakai to Mt. Shirouma-dake. It will be a fantastic ridgeline walk with a wide open view. As you come closer to the summit, mountains on the south side of Mt. Shirouma-dake appear in your sight. Then you will reach the summit of Mt. Shirouma-dake, where many hikers are resting. Enjoy an impressive view. Staying for a night at Hakuba-sanso Mountain hut or Hakuba-dake Chojo-sanso Mountain hut is recommended. There is a camping site at Hakuba-dake Chojo-sanso Mountain hut.

On the final day, please descend the famous Hakuba Massive Snowy Gorge, the large snowy valley. Great caution needs to be employed on the steep slope from the emergency hut to the beginning of the snowy gorge. Descending the snowy valley will take about 1 hour and 30 minutes. Crampons might not be necessary but two trekking poles might be useful when descending. Carefully follow the red line. Also be cautious for falling rocks. From the end of the slope, Hakubajiri will be reached shortly. From there, take a logging road to Sarukura for about 50 minutes.
