Sleeping

Libertador General San Martín is a sizable sugarcane town with little charm but several places to stay. Little Calilegua is more appealing, with a tumbledown tropical feel and a deafening chorus of cicadas around the historic Sala de Calilegua estate. There's also a free campground at the entrance to the national park, which has bathrooms and shower, but no power, drinking water or store.
