I will be traveling to San Pedro de Atacama this October and will have a precious two day period to spend seeing the area. I have a few questions I was hoping some of you might be able to answer. First, how reliable is air travel to this area? I will be flying LAN. Second, I would love to hear recommendations for the best tour company in the area. I do not mind paying more for exceptional or private guide services. I am happy to trek and to be at altitude, as I will have just finished a trip to Machu Picchu. I have read many of the previous threads on this topic, but haven't been able to reach anyone to book excursions in advance just yet, despite multiple e-mails. I have so little time in the area and would like to make the most of it! Any suggestions would be most welcome.
