Information from Travel Taipei
Built in 1931, the stately pristine Zhangshan Temple boasts an Avalokitesvara-resembling stone discovered around the 1910s. Due to frequent reports of miracles involving the stone, followers decided to enshrine it in a new temple. The current appearance of the Temple is the result of a series of renovations. The Zhangshan Temple commands a perfect view of downtown Taipei. On holidays, many hikers and pilgrims enjoy the three hiking trails near this prominent temple in Muzha’s tea-growing area.
There are several ways to the temple. As a local people, I recommend you taking the hiking trail. Though the gz is beside the road, you might face to the parking problem because of few parking spaces. Don't drive here in blossom season, you will get in stuck in traffic jam in the mountain.
