The expedition begins in Copiapó, the closest major city to Ojos del Salado. The nearest airport is CPO (Desierto de Atacama Airport). We may also arrange pick-ups from nearby towns like Caldera or Bahía Inglesa if preferred (both villages with accommodations close to the shore of the Pacific ocean), but the recommendation is to begin in the major city (to ease the departure and buy the last supplies) and to finish the trip at the sea!
