The flight from La Paz, Bolivia into the jungle is a much better ride than anything at Disneyland. La Paz is built in a little valley the breaks up the monotonous altiplano – a super high-elevation plain that makes up central-western Bolivia. Its main avenue runs along where the river must have been. The walls of the valley, which are now mostly built up with humble concrete houses, resemble the odd rock formations of the Badlands of South Dakota.
