Rio  has some lively outdoor markets, most of which are held on the weekends. The most famous is Ipanema ’s Feira Hippie (Praça General Osório, Ipanema, 9 a.m.–6 p.m. Sun.). It features a crowded but lively hit-and-miss jumble sale atmosphere that attracts an awful lot of tourists (and pickpockets) and is somewhat overrated.
If you happen to be in the otherwise deserted Centro  on Saturday between 9 a.m. and 5 p.m., you might enjoy browsing through the cornucopia of antiques and bric-a-brac on display at Praça XV ’s Feira de Antiguïdades. On Sunday, the same goods migrate to Gávea ’s Praça Santos Dumont.
For more contemporary wares, head to the Babilônia Feira Hype, which takes place on alternate weekends at Gávea’s Joquei Clube  (Praça Santos Dumont 131, 2–11 p.m. every second Sat.–Sun., R$5). This large combination flea/fashion market has an interesting assortment of clothing, jewelry, and design pieces by up-and-coming Rio designers as well as various outdoor eateries with views of the nearby racetrack.
