I recently met an Uber driver in Chengdu who has a side business where he organizes weekend trips to go kayaking, canoeing (and camping) outside of Chengdu. If anyone is interested, add me on WeChat and I will send you the contact info.
This is something I have been passively seeking in Chengdu for a long time and I am happy to have stumbled upon it. This guy organizes small groups to go a few hours out of the city via bus or personal car depending on group size.
