Roca Cuadrada Hostel

This hostel by the sea is spartan but sleek with an unrivaled position on the sand. Dorms hold no more than four beds and there's a shared kitchen, storage space for water-sports equipment and a bar overlooking the ocean that's lively on weekend nights. The on-site surf shop offers 1½-hour lessons (private/per person in a group CH$25,000/20,000).
