Montreal has 18 indoor or weather-proof family activities, and several of them — the Biodome, Pointe-a-Calliere's underground ruins, and the Science Centre — are actually better experienced on a rainy day when you're not tempted to be outside. The city also averages 162 days of precipitation per year, so locals have this figured out.
Here's what works when the weather turns, organized for fast decision-making.
Best Indoor Museums and Cultural Spots
Pointe-a-Calliere Museum — Underground archaeological ruins at Montreal's 1642 founding site. Kids descend into tunnels with original stone foundations and artifacts.

Restaurants Worth Lingering At
When you need to kill 2 hours with good food and a warm, dry space.
Juliette & Chocolat — An entire restaurant built around chocolate. Fondues, brownies, crepes, and thick hot chocolate. $50-80 CAD for a family of 4 for desserts and drinks. Share a fondue — portions are generous. Warm, cozy, and toddler-meltdown-tolerant. 45 min - 1 hour.
Au Pied de Cochon — For families with adventurous eaters. Loud, casual, and theatrical — the duck in a can and foie gras poutine are worth the splurge. $200-350 CAD. This is a memorable rainy evening. 1.5-2 hours.
Schwartz's Deli — The tiny, packed deli with the best smoked meat in Montreal. $60-80 CAD for a family of 4. The line is part of the experience — watch the meat being sliced through the window. 30-60 minutes.
La Banquise — 30+ poutine varieties, open 24 hours. $50-70 CAD for a family of 4. Takeout lets you skip the line and eat at nearby Parc La Fontaine — though on a rainy day, eat in. 30-60 minutes.
