Changes

From "Plaza de Armas", go West (opposite of the church). Continue down for 650 meters to the Mall "''Puerta del Mar" '' (there is a Lider and a Sodimac there as well). Before you get to the pedestrian bridge that makes you cross crosses the big road to the MalltheMmall, there are the buses that go to Vicuña / Pisco Elqui. Take any of them and ask to be dropped of at the airport. It should cost you 800 pesos (as of June 2016). When you exit, you can walk 10 minutes more further in the direction of the bus. There , there is a bus stop there which that makes a perfect spot. I got picked up in 20 minutes.
