The Atacama's landscapes vary dramatically between salt flats, lagoons, valleys and high geothermal areas. A short map distance can involve a substantial change in altitude and conditions. Compare the forms of the land, but let the practical realities determine the order of excursions.
Use a suitable base and current local guidance to build a measured sequence. Confirm the elevation and demands of each outing rather than treating all day trips alike.
