Rio de Janeiro With Kids
The tricky part of Rio with kids is not finding things to do, it is finding water that is actually safe for a small child to swim in. Once that is sorted, the aquarium, the botanical garden and a redeveloped zoo cover a full week of mornings.
AquaRio, South America’s largest aquarium
At Praça Muhammad Ali in Gamboa, AquaRio holds 4.5 million litres of saltwater across 350 species, including a 20-metre transparent tunnel walk beneath sand tiger sharks and rays. It opens Monday to Friday 09:00-17:00 and weekends and holidays 09:00-18:00, last entry an hour before close. Foreign-visitor adult tickets run R$150, Mercosur and Brazilian-resident tickets R$110-120, and children 3-11, students and seniors R$75-80; under-3s go free. Book AquaRio tickets ahead on GetYourGuide , since weekend slots fill through the official AquaRio booking system .
BioParque do Rio
The old Jardim Zoológico in Quinta da Boa Vista was closed, privatized and rebuilt from the ground up as BioParque do Rio, replacing iron-bar cages with immersive biome enclosures for conservation species including the golden lion tamarin. It is open Wednesday to Sunday, 09:00-17:00, last entry 16:00, and closed both Monday and Tuesday. Concession tickets start around R$25 through the official ingressos.bioparquedorio.com.br portal ; confirm the adult rate there before you go, since the printed price ladder changes between seasons.
Jardim Botânico
Founded in 1808, the botanical garden’s 54 hectares include the 740-metre Avenue of Royal Palms, Victorian greenhouses, giant Amazonian water lilies and wild capuchin monkeys along flat, stroller-friendly paths. It is open Tuesday to Sunday 08:00-17:00 and Monday 12:00-17:00. Pricing is tiered by residency: R$73 for foreign visitors, R$55 for Mercosur residents, R$32 for Brazilian residents nationally, and R$19 for Rio state residents; children under 5 and seniors 60+ enter free. Book through the official jbrj.eleventickets.com system .
Parque Lage
At the base of Corcovado, this 52-hectare park wraps an Italianate 1920s palace around a reflecting-pool courtyard, with stone grottoes and artificial ruins kids can explore. Grounds are free, open daily 09:00-17:00. Stick to the park itself with children; the hiking trail that climbs from here toward the Corcovado summit has a documented pattern of armed robbery and is not a family walk.
Where to actually swim
Copacabana, Ipanema and Leblon look inviting but carry real dumping shorebreaks and rip currents unsuitable for small children. Two spots are genuinely calm: Praia Vermelha in Urca, a sheltered 200-metre cove between two hills with coarse sand and gentle surf, and Posto 6 in Copacabana, protected by the old fort’s breakwater, with shallow water and paddleboard rentals nearby.
The verdict
One aquarium day, one botanical-garden morning, and an afternoon at Praia Vermelha covers a family week without a single dangerous shorebreak. For a plotted-out week that fits these stops around the rest of the city, see the 4-day Rio de Janeiro itinerary . For hotels near the South Zone beaches, compare options on Booking.com .
Before you go
Book AquaRio and BioParque time slots online before a weekend visit; both sell out their morning entry windows by mid-morning during school holidays.
