You can absolutely visit Quebec, particularly Quebec City and Montreal, without a car; in fact, it is often preferred. Both cities are highly walkable, especially in their historic cores like Old Quebec (Vieux-Québec) and Old Montreal (Vieux-Montréal). Montreal boasts a world-class underground "RESО" network and an efficient Metro system that connects major attractions. Quebec City is more compact, though steep; the Funiculaire du Vieux-Québec can help you navigate the Upper and Lower Towns without a hike. For travel between these two major hubs, the VIA Rail train service is the "gold standard," offering a scenic 3-hour journey with Wi-Fi and comfortable seating. Additionally, the Orléans Express bus network provides frequent, reliable connections to other regions like Trois-Rivières or Gatineau. If you wish to see nature, many tour operators offer day trips from the city centers to Montmorency Falls or Jacques-Cartier National Park, eliminating the need for a rental vehicle entirely while allowing you to avoid the high costs of parking and the stress of navigating winter driving conditions.
