淡水 - 陽明山國家公園遊客中心

I didn't go there since a long time but I think it's my best track in Taiwan from what I know!

7 mountains and 13,000/ 14,000 steps to climb: a hard way to go there.

Only two troubles: there are no water point on the way... And we need to be free for at least a half day (5 hours of climb + 1 hour of bus between 陽明山國家公園遊客中心 and 士林夜市 + 30 min between 士林 and 淡水 or 台北).
