I'm not sure what you meant by unavailable to tourists. Nobody forces you to stay with a tour or anything, it's not like North Korea. Of course, if you stick to a guided-tour, you probably won't see too much. If you leave the city, you can find plenty of backpackers. The friendliness probably has more to do with the culture being more laid-back then political freedom.
