Píngxī 平溪 is centered on a mountain valley to the east of Taipei 台北. It was an important mining center from Japanese times to the post-war era but was almost abandoned when the mines closed many decades ago. Recently the entire area has undergone a tremendous revival, becoming one of Taipei's top attractions. Pingxi is served by a picturesque and romantic railway spur line of the same name. There are some great hikes in the area, several old streets, sky lanterns, and lots of other things to see.
