If you can't get with an organized hike, you can still get some great walking done in Taiwan. There are books available on local day hikes. The Saunders book on day hikes 2 should still be available at any Eslite Bookstore - I like the one across from National Taiwan University. That book has directions to Bei Cha Tian Shan (north piercing sky mountain). Of all the walks I've done in the Taipei area this was the biggest kick in the ass. I really liked it and didn it several times. Don't bother with the peak itself unless you like tripping a lot; just hike to the old forest. The people you meet along the way will not be great in number but they are the best. Take food and water. If you have a stove you can cook up some tea at the top. That's more important in winter.
For extended hikes, you're going to have to get a response from someone or rely on whatever the national parks provide. I've done extended hikes and have camped out recently over the hill from Neiwan. The nice fellow there said he could take me up further in the hills when I get back next time and there is a Japanese era stone trail that was used to pacify the mountain areas by getting police in from Daxi (Daxi) quickly. The hikes and trails are there and you have to give them a little respect if you go up very far. Take a stick for keeping from falling and for defending yourself from the poor dogs that have been released in the hills. A bitch with a pup will attack you and think nothing of it - literally.
Otherwise, it is really really beautiful.
