tiger leaping gorges & minorities ethnic

For tour agency, I think TravelChinaGuide is not bad. I joined their tour last year to go to Li River area. They helped me to arrange trips to Longsheng area to see how the local people live. Besides, they also took to other minorities, which left me deep impession. You can contact them by sending them emails at travelchinaguide.com|tours and tell them your requirements. They will help you to arrange well before you arrive in China.
For Yunnan, I think you can go to Lijiang and Dali, which cannot be missed in the province.

Thanks!
Are you meaning ethnic minorities in the area of Guizhou? I was thinking to go to the south of Yunnan for this.

Hello, Geo. I did not mean that. Lijiang and Dali are in Yunnan where you can also find many ethnic minorities. You can just tell the tour agency your requirements to see the minorities groups in YN, they will help you to arrange.
