The state of Rio de Janeiro has the third longest coastline in Brazil. Backed by jungle-clad mountain ranges and sparkling lagoons, it spreads out for more than 635km from Rio itself, encompassing vast beaches and the huge, island-studded bays of Guanabara, Sepetiba and Ilha Grande. To the north is buzzing Búzios - once the preserve of pirates, slave traders and fishermen, now a chic beach resort frequented by fashionable, well-heeled Brazilians; to the south, along a lush coastal corridor known as the Costa Verde, are unspoilt turquoise coves, velvet green peaks, sleepy fishing villages and the colourful colonial town of Paraty. With a fast, modern highway running the entire length of the state, it’s a beautiful and easily accessible place to relax and recharge after a few frenetic days in the city.
