Pingxi
Today we went to Pingxi (平溪), because it was a ride that we had to do after having passed the sign so many times on the way to Shiding. A leisurely and easy ride without any really steep, challenging hills. From Pingxi we continued a bit further, to Shifenliao and the waterfall there, before turning back to Taipei. Back home again, we had clocked up 80km in a great sunshiny ride.
Pingxi can also be reached by the narrow gauge train that runs between Ruifang (瑞芳) and Jingtong (精同). The views from the train are better than the views you get from the road.
Facts From Taipei, follow route 106. It's as simple as that. Jingtong is worth a stop for a refresher or a bit to eat because of the Japanese era station house which is on a short strip of generic Taiwan Old Street. There are also a couple of mountain hikes to be had in Jingtong and Pingxi
