Walking 2:45:00  9.5 km (17:22 / km)
Walking on Miyajima Island, Hiroshima's equivalent of Rotto, except it has deer instead of quokkas, not to mention a 535m mountain and numerous Shinto/Buddhist temples. Plus numerous food and souvenir outlets.
From the ferry we set off up the first part of the mountain, meeting some deer within the first 400m. There was a road for about 2.5km to the ropeway (Japanese term for cable lift), which we had intended to take, and goes to around 450m, but still a good km from the summit. It saves around 2km of steep path - mostly steps actually, and 250m of climb, but is 1.3km long (according to my gps: I left it in the distance, because I can). The first part of the lift, around 800m long is in a small car taking 6 people, then you go up about 50 stairs to get on a bigger car with a capacity of about 30 for the remaining 500m. Fantastic views across the inland sea and back to Hiroshima with mountains behind.
On exiting the cable car, with a full day ahead (we had to get back to do the Peace Park and museum) we decided to give the summit a miss. This still meant 5km or more of steep, mostly down but with several uphill sections to go back a different way eventually coming out at the temple at sea level ( parts of it are literally on a beach). Mostly stairs too, and mostly tricky rock stairs.
We did stop off at a shrine which claimed to have a fire lit by a monk 1200 years ago and burning continuously since. Supposedly it is a lovers' shrine, as the flame represents eternal love, so we bought an incense stick each and lit them (see PP's fb page).
The stairs were hard on the knees, but we made it back down and searched fruitlessly for an ice cream shop which had been highly recommended, PP's phone was running low on battery by this time so couldn't use Google maps.
A 20 minute ferry ride, 30 minute train and 20 minute tram took us to a vegan cafe near the Peace Park where we had one of the best (and cheapest) meals of the trip so far, before visiting the very moving park and museum. Probably walked around here for at least the distance that I squibbed on the cable car, so there!
