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.
Worth the trip - on a beautiful day, the view is stunning.
Even with the cable cars to the top, there is still quite a bit of walking to reach the summit.
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.
Mt. Misen and Miyajima island are well worth the trip. Visited on a Saturday and the trails were fairly busy on the way down. The cable cars were down for maintenance, so we hiked up the mountain. Incredible views and a great workout to get to the top.
