Santa Catarina's swankiest seaside town, Praia da Rosa, has two main attractions: a set of stunning, nearly pristine beaches and a sophisticated, eco-aware population. Oh, and many opportunities for surfing. In winter, the bay becomes a breeding ground for southern right whales, and mothers and calves can be seen from the beach. Instituto Baleia Franca, a conservation group created to protect and study these unique mammals, is based here.
