Enjoy trekking when you come to Aso!



From the top, you can see Aso's characteristic terrain more clearly. When you reach the top of the mountain, you will feel the magnificent scenery of the world's largest caldera, and you will feel the breath of the people living there.During the mountain climbing, you can encounter the unique nature of Aso, such as the song of birds and cute flowers.

Here are 3 recommended routes around the guesthouse, from easy-to-climb route that are easy to climb even for beginners who can reach the summit in 30 minutes from the starting point to hard route that can be climbed using ropes.

清栄山 Mt.Seiei



It’s a low mountain, so the scenery is not good? No! at the top, you can see the magnificent scenery unique to Aso!            
In autumn, the silver grass field shines golden at the summit. We also recommend for families.
