Huacachina Huacachina Huacachina is a natural desert oasis, just outside the city of Ica. There’s a small lagoon, surrounded by high sand dunes. There are maybe a hundred residents and thousands of visiting tourists each year. It was once a getaway for Peru’s elite, a secluded garden to enjoy nature and relax. It’s a cup like valley in the midst of massive sand dunes. Most people either ride dune buggies, sandboard, or ski down the dunes.
