What are some interesting (rural?) areas to visit in China for seeing nature and wildlife? I'm looking to go for short hikes on relatively untouched (or restored) natural areas, get a chance to see local wildlife/birds, and preferably avoid big crowds (which is probably difficult in China). Perhaps something similar to what one might find in some US national/state parks.
I'm looking for relatively accessible and affordable places, which rules out the obvious choices of Tibet (extra visa needed) and probably Xinjiang too. The question is general for all of China, but I'm particularly interested in places close or in Hubei.
I would prefer answers based on personal experience (from people who've been there).
