Amazing trip, from the Atacama Desert to Patagonia both in Chile and Argentina. All accommodations were unique and very comfortable a yurt, ranch with generator for power, eco hotel built into the side of a mountain, and the ubiquitous hotel. The Atacama Desert week was our first week using Quasar we had no guide for this week, We live at 9,000' hike daily and wanted to summit a volcano at 18,500'. Quasar worked with the hotel advising them we lived and hiked at high altitudes with that information the hotel fast tracked us and we were successful in our climb to 18,500', followed by champagne at the hotel! This hotel had great food and our guide was perfect! We had a private guide during the Patigonia trip and he was the best part of the trip, we met and set a tentative plan that was flexible to take into account weather and what we wanted to do. We are not into much drive, sight see, drive stop, drive.....but more but more relaxed hiking in one area. I am a student of paleontology and Quasar set up two separate tours with additional guides to visit paleo sites. One site was with the paloebotanist who was working the site! We were able to do some special hikes those without a guide could not do, best part he found a puma!!!! I recommend a guide! One hotel cancelled several of their daily trips and guests were not happy. We always had a back up plan, became good friends and had a unique trip because of our guide. He knew birds, off the beaten path hikes, places to stop and became a great traveling companion. I could go on but I highly recommend Quasar.
