Jiufen (九份) is another old mountain town in Taiwan turned into a tourist destination, similar to Pingxi (平溪) and Shifen (十分).
Before leaving Taiwan, I saved the best for last – Pingxi, a scenic area about an hour and a half away from Taipei by train. This area is actually a collection of towns – Pingxi (平溪), Shifen (十分), and Jingtong (菁桐). All used to be known primarily for coal mining, but have since become a major tourist attraction, especially with tourists from the mainland. This area has decent scenery, but is primarily famous for its sky lanterns.
