Sagano Scenic Railway also known as the Romantic Train runs along the Hozugawa River from Arashiyama to Kameoka. From this lovely old train with open carriages and wooden bench seats you can see the most wonderful scenery.
You can purchase a return ticket or come back on the Hozugawa River Run. The day we did the trip the River was closed due to heavy rain. I have done the River Run and it was heaps of fun.
