No direct bus from Anshun to Kaili. You can take bus to Guiyang (about 3-3.5 hours), then change bus to Kaili (1.5 hours). If you plan to visit Huangguoshu Waterfall, you can get to the waterfall from Anhui (one hour) then take direct bus to Guiyang (2 hours).

From Kaili to Sanjiang: Seems no direct bus too. Suggest you go to Rongjiang (about 5 hours) first and then go to Sanjiang. you can also make a transfer at Congjiang from Rongjiang to Sajiang. In deed, Sanjiang is close to Guangxi. If you have plan to Guangxi, You can get to Sanjiang from Guiling, which is only 180 km from there.

Thank you for your reply Mr John. We are flying back via Guilin and also plan to visit the Chengyang Wind and Rain bridge which v missed during our earlier trip. We will b visiting the waterfall, so how do u suggest v shd travel. Means v take a bus from Panxian to Guiyang, then to Anshun.
