A quieter and calmer answer to Rio and Sao Paulo (although guaranteed to be far from tame during World Cup), Brazil's inland capital is known for its modernistic architecture envisioned by native son Oscar Niemeyer, whose curving designs pay tribute to the shapeliness of the country's legendary ladies, naturally. Soak up the cityscape at spots like the Palácio da Alvorada and the stunning Cathedral of Brasilia, then make for Lago Paranoá, a man-made lake just east of the city where you can go kitesurfing or sailing and even head underwater with a tank strapped to your back to dive the ruins of an old submerged village.
