Hi all.
As I have been scheduled 4 rest days in May, I'm looking to take this opportunity to go Taiwan again. I've been to Taipei thrice, taichung once and hualien once.
Cause this trip wasn't plan until 2 days ago, I only have less than 1 week to decide on my itinerary. I'm a female and will be travelling alone. Any ideas where else I can visit for scenic areas? I don't mind doing a bit of hiking, biking or joining some local tour group. But I'd hope to stay in an area for at least 3 days (to slowly explore the area entirely) till i head back to taipei to catch the flight back. I'm also going on a tight budget as I'm back from a Tokyo trip last month.
Tried to google places with backpackers inn, but results only show Hualien and Taipei.
Any suggestion is greatly appreciated. Thanks much!
