These are hiking trips in Yunnan and Sichuan that require at least one night on the trail in order to complete. See Camping/Backpacking Tips for more information on what to bring on an overnight hike.
Some of these routes are more established than others. Some you will see large crowds and others you won't see a single other person. For all of them, don't rely solely on our description, make sure you do some outside research, know what you are doing/where you are going, and have an emergency plan in place in case something goes wrong.
