Valle de la Luna is an interesting geological formation slightly south of Bolivia's capital La Paz. It looks similar to the Bryce Canyon but in much smaller scale and not much colors other than straight brown dirt color. Basically the geological formation of endless spiky spires are erosion of clay rather than rocks. There are still some colors in those spikes as the mineral contents are varying from one place to another. You can walk through the Valle de la Luna on the boardwalk. For those who are familiar to the Bryce Canyon, it is more of disappointment than excitement when you see and walk through it. The collectivo from the center of the town near Plaza Murillo comes directly on the Valle de la Luna, so access is rather easy.
