On a relaxing autumn weekend afternoon, I took a trip down the river surrounded in beautiful autumn scenery. There are many branches around this area, but the Arakawa line is the longest course. It was very refreshing to be rocked on a boat whilst enjoying the amazing view. Unfortunately, it was cloudy the day I visited, but you can enjoy the sunset when you ride around 15:30 so I definitely recommend it.
