Muzha to Pinglin
Here's another way to get to Pinglin (and beyond) from Taipei. This route is a little longer as you are going all the way to Pinglin. From the Muzha or Zoo MRT station, ride Wenshan Rd (aka 106乙, just south of the 106) to Shihting. At Shihting you have different choices for getting to Pinglin: stay on the 106乙, or take the 北47 and then connect with Provincial Hwy 9 to Pinglin.
