If you can get yourself to the National Palace Museum front car park (Zhi Shan Road, on your leeft as you come from TianMu) at about 7:45 on saturday morning (unless its absolutely pissing down) I can meet you there for a good introduction to the best that YangMingShan has to offer: the Satellites (550m) and the Saddle (800m). Bring a road bike with climbing wheels…max grade about 18%, average about 8%
