Our trip to Guiyang and surrounding areas - Rafting and Canyoning

Coming July we will travel for 1 week as part of our 3 weeks holidays! We really like to be off the beaten path and also the climate seems surprisingly acceptable in July. We found such nice spots already but the activities we did not find yet are rafting and/or canyoning. We are looking for a day canyoning and rafting through an experienced agency/company. There should be some as I heard..... Thanks in advance!!
