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.

MIANTIAN SHAN AND XIANG TIAN CRATER POOL (面天山/向天池)
Miantian shan trail offers an easy to follow path over some of Yangmingshan National Park's western peaks. Go immediately after heavy rain in order to catch sight of the elusive xiang tian crater lake.
XIAOGUANYIN SHAN LOOP WALK (小觀音山O型縱走)
A moderately difficult and very fun loop hike with absolutely stunning views over Yangmingshan Park's bamboo cloaked northern hills. This is one of my favourite walks in this area and a must for anyone seeking to get away from the crowds at Qixing peak.
QINGTIANGANG CIRCULAR TRAIL (擎天崗環形步道)
A gentle and incredibly scenic circular route around the famous, cow-grazed grasslands of Qingtiangang in Yangmingshan National Park. This trail is accessible by public transport and should be ok for anyone who can handle some steps and an uneven walking surface. Make sure to come on a clear day, (when you can see Qixing Mountain peak from the city), in order to enjoy the views at their best.
