from travelling 3 years in South America here‘s what I know about tribal communities from Rainbow Family and more communities who are connected to freedom and nature. South America has a lot of wilderness and conscious spiritual people living sustainably in communidad. I would recommend Argentina and Chile because there are a lot of alternative people there and many rainbow communities. I know of at least 5 rainbow crystal lands between those two counties, (a rainbow crystal land is a ”we are all equals/Peace and Love) community” which is free and open all year round to everyone. For specific information you will have to dig a bit deeper, but I know there you will be able to find. ask the people You meet Around Who are artists and musicians About communities. The Andean mountain range is full of beautiful places especially parts with rivers and low pollution. Anyway I would recommend going, ask me if you have more specific questions.
