If you're brave and looking for adventure, you ought to check out surfing. Luckily, Rio is a perfect destination for such a sport. In winter (late April–October) the ocean is most turbulent and the waves are formidable. The most popular places for this exciting water activity are Barra da Tijuca—the city's longest beach, Macumba, Prainha, Grumari, and Guaratiba. Just an hour ride north from the city you can find Saquarema, Buzios and Cabo Frio beaches as well.
