Rio has some of the most beautiful beaches in the world; not to forget the most skimpiest bikinis. That's the norm here, so one better not stare. TIP: Besides the beaches, explore the city & see the beautiful architecture. The cable car ride to the top of Sugar Loaf Mountain (Pao de Acucar) offers beautiful views of the city. Ride it at sunset if you can.
