丹後縦貫林道(丹後半島太鼓山へ) Kyoto Jukan Rindo (To Mt. Taiko, Tango Peninsula)
Today I went for a 72 km ride. From Miyazu cross Amanohashidate, go to Otokoyama, Iwataki, then take prefectural road route 53. Turn off on to Tango Jukan Rindo (Nariai Line) and stay on it to Mt. Taiko. From here head down to Yoro town and back along the coast to Miyazu. There is a lot of road works atm, so it would be impossible to do this route without a mountain bike and it would have to be on a Sunday.
