If we could give Oscar 6 stars we would.  

He went above and beyond to make our experience seamless and unforgettable.  

He showed us the best the Atacama Desert has to offer.  He is extremely passionate about his job and clearly enjoys meeting people and showing them the sites.  He has been doing tours there for 20 years, and he knows how to perfectly organize your trip; what parks are open and when, making sure you see the desert highlights, not the crowds of tourists.

Oscar's tour had a lot of special touches: pisco sour at sunset overlooking the most fantastic sites, delicious breakfast and lunch spreads...  For example, our morning at Tatio Geyser was freezing, and after we got out of the thermal pools he had prepared a beautiful table with a hot breakfast including eggs and coffee overlooking nature.  Not to mention the dozens of times he stopped the car for us to take a picture of nearby wildlife and llamas!

Since Oscar is fluent in English, the quality and information given during the tours was well beyond what we would normally expect.  He is so highly knowledgeable on all topics, and able to clearly communicate history, geology, etc of all the sites that you visit.

In addition to the fantastic excursions, Oscar was very accommodating and flexible.  For example, when our flight to Calama was severely delayed due to weather, he waited for us for hours at the airport to pick us up.  Not only that, he moved the excursions we had missed due to the flight delay to the following day.  He worked overtime to make sure we didn't miss any of our planned excursions.

Needless to say, if we go back, we will definitely be booking with Oscar!
