An author of Lonely Planet Taiwan, Robert Scott Kelly also edits a blog called PASHAN HIKING THE MOUNTAINS, VALLEYS, RIVERS AND JUNGLES OF TAIWAN.
Taiwan offers more hikes, on more varied terrain, within one compact region, than almost anywhere else in the world.
In 2005 Robert and a friend climbed Snow Mountain (Xueshan, 雪山) and posted a detailed trip report on the standard 3-day hike.
I was particularly interested to read about his startling a bear.
Bears in Taiwan?
Yes, a few Asian Black Bears survive there.

I’m definitely planning on hiking Taiwan one day.

It’s a good read – Snow Mountain (Xueshan, 雪山)
