Curitiba hands over its best sights for nothing: thirty-odd free parks, quarry waterfalls, immigrant memorials and a Sunday fair where lunch costs R$15. One R$6 BRT fare with free transfers inside the tube stations links almost all of it.
Curitiba's largest park (1.4 km²) is free and never closes. Capybaras graze the lakeshore at dawn before the crowds, and a 6 km paved loop rings the water. Free outdoor gym, free Wi-Fi and a 1930s hunting lodge inside.
Free German-immigrant woodland in Vista Alegre. The Trilha de João e Maria walks Hansel-and-Gretel panels down the hillside, the wooden Torre dos Filósofos frames a rooftop city view, and the Oratório Bach hosts free concerts.
Free riverside park holding a full-size replica of the wooden São Miguel church, with painted pysanky eggs displayed inside. Open 06:00–20:00, wide packed-earth trails follow the Barigui river and stay almost empty on weekdays.
Built for the pope's 1980 visit, this free park preserves seven 19th-century Polish settler log cabins moved here plank by plank, plus a small memorial chapel and araucaria pine paths. Open 08:00–20:00, entry to the cabins costs nothing.
Sunday-only street fair, 09:00–14:00, spreading over 1,000 stalls across the cobbles of the historic quarter. Entry is free; a pastel runs about R$12, caldo de cana R$8 and grilled cheese on a stick R$10.
The 1958 city market at Av. Sete de Setembro 1865 trades Tue–Sat 07:00–19:00 and Sun 07:00–13:00. Its upstairs food court plates a prato feito for R$25–35, and the organic wing has the cheapest fruit downtown.
A steel-and-glass arcade from 1991 on Rua Visconde de Nácar, free to walk through at any hour. Its kiosks pour espresso for around R$5 and fry coxinhas for R$8 — a warm, dry shelter when the Curitiba drizzle arrives.
On Rua Claudino dos Santos beside the Largo da Ordem, this beer hall pours 300 ml of chopp for roughly R$12 and serves sausage-and-potato plates built for two. Wooden benches spill onto the cobblestones once evening sets in.
A working 109 m telecom mast on Rua Professor Lycio Grein de Castro Vellozo with a glazed 360° gallery near the top — the only public observation deck of its kind in Brazil. Around R$10 covers the lift; closed Mondays.
A tubular-steel opera house floating on a pond inside a flooded granite quarry, free to enter daily 08:00–20:00. The neighbouring Pedreira amphitheatre and its 30 m rock walls open to visitors whenever no concert is booked.
The Unilivre spiral tower, built in 1992 from reclaimed eucalyptus poles above an old quarry lake in Pilarzinho. Free entry Mon–Fri 08:00–18:00, with signposted forest trails and a ramp climbing to a canopy-level lookout.
The finest free sunset in Curitiba: a decommissioned quarry where a waterfall drops between two lakes, joined by a 45 m lit tunnel cut through the rock face. The Jardim Poty terrace above catches the last light over the city.
