Trail description
Day 1: 6h, 8.4km, 1700m elevation gain.
Start from Sarukura bus stop. The hut there has toilets and vending machine etc. It’s possible to stay here to get an early start.
The first couple of hours are mostly in the forest and there isn't much to see.
Once you get out of the forest the scenery is beautiful and you'll soon cross a small stream. This whole area is incredibly beautiful and there is lots of variety with small waterfalls, peak views and a hot spring flowing down the mountain.
The onsen at Hakubayarikoya is 1000¥ for day visitors and so worth it. Be prepared, it's very hot. There is also a womans bath. When we went in October they were already dismantling the hut and we were the only people there.
After the onsen it's another 2,5h to tengusanso, the hut for tonight.
If you have extra time you could also make a detour to Hakubayari which should add about 70min round trip from the fork.
Day 2: 7h, 13km, 630m elevation gain
Today is gonna be a lot more difficult and you'll have to pass the Kaerazu Kiretto (ridge of no return) using chains and your hands. The ridgeline goes up and down on the way to Karamatsu and is very exposed and dangerous in some sections. You'll have to hold your weight on chains and climb over deadly drop-offs. People are scared and slow so expect some traffic if you go on the weekend.
It took us about 3.5h to Karamatsudake and then another 3.5h to Happoikesanso.
The area around happo pond is very busy and good for a break before you head back down with the ski lifts.
Keep an eye on the last time for the lift and start early, otherwise you'll have a lot more to walk on day 2. (Times depend on the day, check here)
