Close to the city, Battleship Rock Trail is an ever popular walk, and on weekends in particular you are likely to find it pretty crowded. But for those who are feeling brave it offers an easy after dark hike and a stupendous night view of Taipei.

GUANYIN SHAN NORTHERN CROSS ROUTE (觀音山北橫古道)
Anyone who has hiked in Yangmingshan National Park and cast their gaze across the Tamsui River towards Bali will have noticed the multiple peaks clustered around Guanyin Shan. This trail covers many of those peaks, and is a much more interesting walk than the stone steps that also climb to the top.
MOUNT POJINJIA (波津加山)
The fourth highest of the Guguan Seven Heroes, Mount Pojinjia is a steep, but straightforward climb that rewards all of your hard work with the occasional spectacular view over distant cloud-capped peaks.
