I lived in this area for two years as a Peace Corps Volunteer. It is truly an amazing people and an amazing cultural experience. The architecture is phenomenal and a prideful part of their lives. There is not a lot of infrastructure develped for tourists. So visitors need to be aware of that and accomodating. Organization for toursits can also be confusing as there is currently no good set up of finding a guide, renting a car, lodging, etc. Try and make sure who you are paying is really a local person and be respectful of the community. There have been some negative effects of tourism already. Children chase cars and people beg for gifts. Don't give out gifts. But always ask before taking photographs and pay them if they ask for money or give them some other small gift.
