To take into account: it is not the fault of Bolivia alone that there are unknown number of tourists in that region: the Eduardo Avaroa National Reserve. A large number of tourists go inside that park, directly from Chile; there are some tourist companies in Chile that even advertise this beautiful place as being Chilean. They come and go as they please.
