The Moon Valley is aptly named. There is no oxygen, its made of cheese and gravity is 0.16 of Earth’s gravity (thanks wikipedia). We took a local bus and got there after about 30 minutes from La Paz. There was nobody else there so we had the whole place to ourselves. It is a surreal place and it’s hard to do justice of the scale of the place with photographs. I wouldn’t really recommend it unlike us you were stuck in La Paz for a few days due to the many strikes Bolivia seems to experience. Which leads to roadblocks.
