I love overland trips, and there is no better place than to experience this adventure than the route between chile and bolivia... From San Pedro de Atacama, you can hop on a small group trek for a few days ride to Uyuni Boliva via the salt flats. You pack up a landcrusier like above and put on your hats/layers because the air is thin and cold out there... you'll see volcano Licanbur close up and the nearby Laguna Verde, whose colors will blow your mind among the browns of the desert... The trips are bare bones, so prepare for a bumpy ride, which really reminds you just how far off the beaten track you are! the refuges are simple adobe walls to protect you from the cold winds at night, simple beds and small stoves will give you a bit of comfort until the next morning when you press on across the desert! A trip that should be on every south america travelers list!
