It was a Great Hike, even when it's very hot cause most of the paths are shaded. But prepare well, since there are no vending machines till you reach the top.
Mount Misen is worth a visit if you are traveling on the island. The easiest way up is by cable car. From the mountain station it is another 30 to 40 minutes on foot. It can be very strenuous, especially on hot days. That's why I recommend buying enough water down in the valley. Water is much more expensive up on the mountain. There is a great view of the sea and the landscape from the top.
Totally worth it. Consider that the trail is not flat and I can assure its longer than it is told on the signs (medium difficult). I recommend to take the ropeway on the way up and come down walking in the direction of Daishoin temple to spot several nice shrines and temples.
We had a pretty clear day so the views were nice at the top. There's a little rest area with views you can hang out at once you reach the top.
Be ready for a hike to the summit and be mindful of the time the lifts close because you don't wanna be stuck coming down the mountain on foot (that would add another ~4 hours to your hike). The lifts ended at 4:30pm the day we went so had to rush. Each way took about 30 mins with a solid pace.
I wouldn't bother coming to the summit if you have mobility issues as it might be a little too difficult.
Fun thing to do once if you're in the area. Probably wouldn't do on repeat personally haha.
Mt. Misen is situated in the center of Miyajima Island. The mountain was opened as an ascetic holy mountain site by Kukai, posthumously called Kobo daishi. On the mountain are various spiritual sites which remind us of the holy deeds performed by Kobo Daishi. The panoramic view from the top of the mountain is magnificent.
