One of my all time favorite hikes/photography locations in Taiwan is The Four Beast Mountains (四獸山) area. Located within Taipei City limits, these trails are an easy escape from busy city life and have amazing panoramic views of Taipei City and Taipei 101.
The trail system includes Tiger (虎山), Elephant (象山), Leopard (豹山) and Lion (獅山) Mountains and is very easily reached from the Taipei MRT system. In fact, the base of Taipei 101 is only a 15 minute walk from the Elephant Mountain trail head.
If that’s not enough, many of the trails are lighted, 24 hours a day!
