There aren’t many English resources on this hike (YAMAP), but if you’re looking for a stunning mountain range without the usual crowds, Mt. Sennokura is a hidden gem. I first went with a group of six in May 2021, and it quickly became one of my all-time favorite hikes. Start from Tairappyo Trailhead.

Accessibility:

• By Car: There is a free parking lot at the Tairappyo Trailhead, the starting point for hikes up both Mt. Tairappyo and Mt. Sennokura. With around 150 spaces, it can fill up quickly, especially on weekends, so arriving early is recommended.

• By Public Transport: Take a bus from Echigo-Yuzawa Station to the Tairappyo Tozanguchi bus stop. The bus ride takes approximately 40 minutes, followed by a short walk to the trailhead.
