Valle de la Luna

Commonly advertised as 'Moon Valley' in English, this part of the Salt Mountain Range offers stunning clinal and anticlinal formations in a perfectly barren landscape. Almost all tours include watching the sunset there—you shouldn't miss it. The large stone walls resemble those of the Grand Canyon in Arizona, sans river. There are also huge halite (rock salt) strata that produce a knocking sound all day long. This can be unsettling at first, but it's actually harmless. Among its prime attractions are the Grand Crater, the Salt Canyon, the Three Maries and salt mines, the Salt Caves, the Cari Viewpoint (also called 'Piedra del Coyote'), and Valle de Marte (Mars Valley). All tours visit a number of these, but it's virtually impossible to know which beforehand. Summer tours tend to be longer, though, and therefore have a greater probability of including more destinations.
