The splendid Praia Parnaioca is hidden along the southern coastline of Ilha Grande. This idyllic beach, part of the Reserva Biológica da Praia do Sul, is devoid of restaurants and hotels, but camping is allowed on the golden sand. The hike to the beach is lined in bamboo groves where monkeys frolic. After enjoying the sun, head back along the trail to a lovely underwood where a river meanders, lined by scented flowers; ideal for blissful dip!
