There are three trails and a ropeway. The Daishoin Route is the shortest and goes by Daisho-ji, while the Omoto Route is the most challenging. Overall it should take two to three hours.
All three routes (and the peak) are well-maintained, but the trails are wild and have a lot of steep, uneven steps. Bring your own water and use the bathroom beforehand, as there are extremely few of either on the trails.
The views at the peak are spectacular.
Slightly challenging hike due to the elevation and takes roughly 1.5 - 2 hours return (including time for rest, visiting temples along the way and taking photos). Take plenty of water and a couple of snacks to keep you energised. Stunning views once you get to the summit!
I walked up to the observation deck and did the loop in the counterclockwise direction. It is mostly stairs on the way up. A little more pathway on the way down. The trail goes by many shrines and other points of interest that will help break up the climb. The recommendation is to allow 3 hours for the round trip. It took me about 2 1/2 with 30 min spent at the summit. Very pretty day and well maintained trail.
Lovely viewing point at the top of the mountain and worth the climb. There is a little souvenir stall in the building with a very nice friendly man. You can go up 4 different Routes. The cable car is currently out of service until March 10th. I went up the Daishoin route and came down the Momijidani Route. By the looks of it the Daishoin Route is steeper with far more stairs to climb but in my opinion has more to see with shrines, a waterfall and more view points behind you. Was going to go back the Omoto Route but glad I didn't as there is a lovely place for food called Momoji-So at the bottom of the orange trail. I hope you enjoy the walk too 🙂
One of the best thing I did in Hiroshima/Miyajima was to hike here (you can also do it with ropeway). The hike it's medium difficulty, 90 minutes, just be careful because there are signs of venomous snakes although I didn't see any.
From the summit you can enjoy a well rewarding view. Absolutely recommend, also to escape a bit from the city crowds.
