Montréal with kids: Biodome, Botanical Garden and beyond
Mount Royal Tour
Duration: 2-3 hours
What are the best things to do in Montréal with children?
Top five: Botanical Garden plus Insectarium combined ticket (~$25/adult), Biodome (budget for reentry with young children who tire quickly), Cosmodome Laval (excellent for ages 5–14), Lachine Canal cycling, and Marché Atwater for food. La Ronde suits ages 8–16 only and is not the first choice if you have younger children.
Montréal for families: more depth than most expect
Montréal is an excellent family destination that gets underestimated by travellers focused solely on food and nightlife. The city has invested significantly in child-oriented attractions, many of them excellent. It is also — unlike Québec City’s cobblestone historic core — broadly accessible with strollers and young children.
This guide focuses on the specific attractions most relevant to families, with honest assessments of what delivers on its promise and what overcomes its limitations less gracefully.
The Espace pour la vie cluster
Four attractions in the Maisonneuve Park zone function as an interconnected family science and nature complex. They are close enough to visit in any combination within a day.
Biodome
Located in the former Olympic velodrome (a spectacular arched building from the 1976 Olympics), the Biodome recreates four American ecosystems under one roof: the tropical rainforest, the Laurentian maple forest, the Gulf of Saint-Laurent marine environment, and a subpolar zone.
The experience: The renovation completed in 2020 expanded visitor capacity and improved circulation. The tropical forest is warm and lush — a welcome contrast to Montréal winter. The Laurentian zone has otters and beavers in active environments. The polar section has penguins (Atlantic puffins and Little Blue penguins, not Adélie).
Honest assessment: The Biodome is good but not exceptional. Some visitors expecting a traditional zoo are underwhelmed by the relatively small number of visible animals. Children aged 5–10 respond most positively. For families with children under 5, the single-level layout and compact distances are manageable. Allow 1.5 to 2.5 hours.
Admission: ~$25/adult, ~$18/youth (13–17), ~$14/child (5–12). Children under 5 free. Combining with other Espace pour la vie attractions via the Carte is more economical for a full day.
Practical tip: The Biodome can be hot and crowded in peak July conditions. Book timed-entry tickets online to avoid queuing.
Botanical Garden (Jardin botanique)
The Montréal Botanical Garden is one of the largest in the world — 75 hectares with 22 000 plant species across 20 thematic gardens. For families, the most engaging sections are:
The First Nations Garden: A living landscape interpreting the plant knowledge of Québec’s Indigenous nations. Educational panels at child height.
The Chinese Garden: A walled classical garden (the largest outside China) with pavilions, bridges, and a seasonal lantern festival in autumn. Children appreciate the architectural drama even without botanical interest.
The Rose Garden: Less educational but visually stunning in June and July, and easy walking for all ages.
The Insectarium: Adjacent to the Botanical Garden with the same entrance ticket, the Insectarium was completely redesigned and reopened in 2022 as the Insectarium, Living Insects Collection. The new concept is immersive: visitors move through spaces where butterflies and other insects fly freely around them. This is a genuine highlight for children aged 4 and above. Allow 1.5 hours minimum.
Admission Botanical Garden + Insectarium combined: ~$25/adult, ~$20/youth, ~$13/child. The combination represents the best value in the Espace pour la vie cluster.
Planétarium Rio Tinto Alcan
The city’s planetarium has been completely updated with digital projection systems. The daytime children’s programme (Planètes en vue) runs on weekends and weekdays in summer — a 45-minute dome show appropriate for ages 5 and up. Evening shows are more advanced.
Admission: ~$20/adult for shows. The building itself (free admission to lobby) has interactive astronomy displays.
Biodome + Botanical Garden + Planétarium logistics
All three are within 10 minutes walking of each other in the Maisonneuve Park zone. The Pie-IX métro station (green line) drops you adjacent to the Biodome. Parking is available off Sherbrooke Est.
A realistic family day: arrive at 9h30 at the Botanical Garden + Insectarium (opens 9h), spend 3 hours, lunch at the Garden café or bring picnic, Biodome in the afternoon (1.5–2 hours), Planétarium show at 16h00. Leaves by 17h30 with tired and satisfied children.
Beyond the Espace pour la vie cluster
Cosmodome, Laval
Thirty minutes from downtown Montréal by car (or 40 minutes via métro to Montmorency then taxi), the Cosmodome sits in Laval and offers the best space-exploration experience for children in the province.
The highlights: a full-scale replica of the Apollo 18 rocket, interactive mission simulators where children control (virtual) spacecraft, a scale model of the solar system mapping the Milky Way courtyard, and the Space Camp programme for dedicated 3-day stays.
For a day visit, the main museum is 2.5 to 3 hours and engaging for ages 5 to 14 years. Entry is approximately 24 CAD for adults, 18 CAD for children. Less famous than the Biodome but consistently better-reviewed by families who visit both.
Mont-Royal and Beaver Lake
Parc du Mont-Royal is Montréal’s equivalent of New York’s Central Park, designed by the same landscape architect (Frederick Law Olmsted). The 200-hectare park is free to enter and offers:
Summer: Pedal boats and kayaks on Beaver Lake (~15 CAD/30 min). Swimming is not permitted. Disc golf. Large shaded lawn areas for picnics.
Autumn: The foliage on Mont-Royal reaches its peak in the second and third week of October. The Kondiaronk Belvedere lookout (accessible by path from the parking area) gives the best view over the city.
Winter: Sledding on the slope behind the chalet (bring or rent sleds). Outdoor skating (bring skates — no rental on site, but several shops nearby). The park is lit in winter and stays active on weekends.
Mount Royal guided tour (2–3 hours) — useful for first-time visitors who want historical and natural context for the park. Family-appropriate pace; includes the Olmsted path network and lookout.
Lachine Canal cycling
The Lachine Canal running path from the Old Port to the Lachine neighbourhood is one of the most pleasant urban cycling experiences in Canada. The 11 km path is entirely separated from traffic, flat, and accessible to children from about age 6 on their own bikes (younger in seats). The path terminates near the Lachine Rapids white-water zone.
Bike rentals at the Old Port (BIXI docking or private rental shops). Cargo bikes and child trailers are available from several rental points.
Marché Atwater
One of the best food markets in Canada. Open every day, the Atwater Market covers produce, artisan cheeses, Québec maple products, charcuterie, and prepared food. For families, it is ideal for assembling a picnic to eat by the Lachine Canal 500 m away. Children can try samples at most stalls. No admission, no crowding except on Sunday mornings.
Stewart Museum, Île Sainte-Hélène
Located on the island used for Expo 67 (now the site of La Ronde and the Grand Prix circuit), the Stewart Museum occupies a British fort dating from 1820. The collections focus on Montréal history and military heritage. The fort itself is the attraction — the building and its surrounding grounds give a tangible sense of colonial history.
For children aged 8 and up. Admission approximately 18 CAD/adult. Less visited than the downtown museums but with more physical space for children to explore.
La Ronde: the honest take
La Ronde is Montréal’s Six Flags-operated amusement park. It deserves an honest mention rather than promotional enthusiasm.
The park has a strong roster of thrill rides (Goliath, Ednör Le Vampire, Cobra) that genuinely satisfy teenagers and adults who enjoy roller coasters. The problem is operational: since Six Flags took over in 2001, the park has aged without corresponding investment. Queue management is poor. Food is overpriced and mediocre. Some rides are closed on any given day without notice. The pricing (65–85 CAD/person) is not calibrated to the quality of experience delivered.
Our recommendation: La Ronde works for children aged 8–16 who specifically want a theme park day, and for whom you have bought tickets online in advance (10–20 CAD cheaper). It is not the best use of a Montréal family day for anyone younger or if the outdoor alternatives are available.
See the full La Ronde guide for detail.
Getting around with children
Métro: The Montréal métro is clean, reliable, and has elevators at central stations (Berri-UQAM, Lionel-Groulx, Snowdon, and others). The orange line covers Old Montréal and Plateau access. The green line covers the Biodome cluster.
BIXI bikes: The city’s bike share is accessible from age 18 but children can be passengers on trailers. The network is dense in the tourist zones.
Taxis/Rideshare: Readily available. Uber and Lyft operate in Montréal.
Car: Not recommended in central Montréal. Parking is difficult and expensive near tourist attractions. Drive only when going to suburban destinations (Cosmodome, Écomuseum Zoo).
Where to stay with children
The Old Port area (Vieux-Montréal) puts you within walking distance of most family attractions. The Plateau Mont-Royal has excellent restaurant access but longer walks to the Biodome cluster. The hotel zone near the Convention Centre (Palais des Congrès) is central but characterless.
For extended stays, apartment rentals (Airbnb or short-term rental agencies) in the Plateau or Mile End neighbourhoods offer kitchen facilities and more space than hotel rooms. Practical for families spending more than 3 nights.

Frequently asked questions about Montréal with kids: Biodome, Botanical Garden and beyond
Is the Montréal Biodome worth it for families?
It depends on your children's ages. Ages 5–10 find the four ecosystem zones (tropical, laurentian, gulf, polar) genuinely interesting. The 2020 renovation expanded visitor space. However, some families feel the experience is shorter than the admission price justifies (~$25/adult). Pairing it with the Planétarium (same ticket zone) and the outdoor Botanical Garden gives better value for money.What is the combined Biodome and Botanical Garden ticket?
Espace pour la vie is the umbrella organisation managing the Biodome, Botanical Garden, Insectarium, and Planétarium on Île Sainte-Hélène and the Maisonneuve Park area. A combined access ticket (Carte Espace pour la vie) covers all four for approximately $55/adult. Individual tickets are around $20–$25 per attraction. The combination makes sense if spending a full day in the cluster.How do you get to Montréal Olympic Park area with children?
The easiest option is the métro: Pie-IX station on the green line puts you 5 minutes' walk from the main Biodome and Botanical Garden entrances. No parking stress, no traffic. Alternatively, drive to the free parking area off Sherbrooke Est. The Biodome and Botanical Garden are within 500 m of each other.Is the Cosmodome in Laval worth visiting with children?
Yes, especially for children aged 5–14 interested in space. The Cosmodome (Laval, 30 minutes from downtown Montréal) has a scale model of the solar system, interactive mission simulators, and educational programming specifically designed for children. Admission ~$24/adult, ~$18/child. Significantly less crowded than the Biodome on peak summer weekends.What is the best free activity in Montréal with children?
Mount Royal Park (Parc du Mont-Royal) is free and offers large open space, a beach at Beaver Lake in summer (swimming not permitted but kayak/pedal boat rentals available), and sleds available to rent in winter for the hill behind the chalet. The Lachine Canal boardwalk is also free and excellent for strollers and cycling.
