Next morning we went to Valle Arco Iris (Rainbow Valley) with Flamingo. Very nice tour, small group, less people in the valley, more relaxed and we had a great guide Sophie (we had 2 very good tours with Flamingo and one very bad, see later posts). We stopped at a viewpoint for brief explanation of the geology of Salar de Atacama and Cordillera Domeyko, metal-rich mountain range named after Polish geologist and engineer Ignacy Domeyko.  In Valle Arco Iris we walked around rock formations colored by various metals and minerals (iron, copper, manganese, gypsum, salt). After late breakfast (great French baguettes) we continued to Yerbas Buenas, at the crossroads of ancient Atacameño trade routes, where shamans recorded important events by petroglyphs. Llama domestication is encoded in the drawings. It is all desert now, with just small rivers/streams, but the landscape was created by large rivers flowing through the area some time ago (Rio Grande). In the afternoon we wanted to visit archeology museum, but it was closed for relocation to a larger space, so we just wandered around San Pedro.

We took pre-booked taxi (expensive) to the airport for an early LATAM flight to Calama. In Calama we took Transvip transfer to San Pedro, fast and efficient. We didn’t realize there is also bus from the airport to San Pedro 4 times a day. In San Pedro we stayed in nice AirBnB in a quiet neighborhood within walking distance from very busy tourist center.  Public transport to attractions is non existent, you have to rent a car (better to do in Calama) or use tours, which we, as most others, did. There are over 80 tourist agencies in small San Pedro competing for your business, our host recommended few of them, but quality depends also a lot on a particular guide. It is all quite chaotic. It is wise to start with lower elevation tours and save the highest for the end of the trip. On our first day we went on sunset tour of Valle de la Muerte (or Marte – Death or Mars valley) and Valle de la Luna (Moon valley) with Latchir, one of few agencies that included Valle de la Muerte. The tour and the guide were good, but the group was quite big. We stopped at Piedra del Coyote for panoramic view of the valley and Salar de Atacama. White deposits are salt as Valle de la Luna is in Salt Mountains (Cordillera de la Sal). Next, we stopped in Valle de la Muerte where people go sandbording and mountain biking. In Valle de la Luna we watched salt formations up close in slot canyons and hiked up a ridge to the top of Duna Major, the highest dune with panoramic views of the valley (Amphitheater) and Licancabur volcano. Walking on the dune is no longer allowed. We stayed there until sunset. It was nice introduction to Atacama desert.
