I'm planning a trip with a friend to the "Tan's" (Kazajastan, Uzbekistan and probably Kirzigiztan). Not sure if it's ok to travel without a travel company. What about visas for Chilean's. What's the must do even though it's touristic, and what's the try to do, trying to go off the beaten path? We are two super fit girls wanting to do a lot of hiking, cool experiences and heading where the wind blows us!
