Furthermore, there was a restaurant and a chalet for tourists. Lots of visitors went to the mountain all-year-round. It was a common entertainment for mid and upper-classes, which spent their days there. VALLE DE LA LUNA - a maze of canyons and giant spires. The formations, composed mainly of clay and sandstone, were created by the persistent erosion of mountains by the area’s strong winds and rains. One of Valley de la Luna’s most breathtaking features is its varied pallet, ranging from clear beige tones to sections of red and dark purple. This natural phenomena is due to the great variance in mineral content between each individual mountain, creating colorful compositions and impressive optical illusions on the eroded hillsides.
