For the vast majority of travelers in 2026, yes, you absolutely need a car in Nova Scotia. While the capital city of Halifax is quite walkable and has a decent bus and ferry system, the true appeal of Nova Scotia lies in its rugged coastlines, lighthouses, and rural charm. Major attractions like Peggy's Cove, the Cabot Trail in Cape Breton, and the Bay of Fundy are virtually inaccessible via public transit. There are very few regional train services, and while some private shuttle companies exist, they are expensive and run on limited schedules that don't allow for much exploration. Having a car allows you to stop at the small fishing villages and scenic lookouts that make the province famous. In 2026, the "Maritime Road Trip" remains the gold standard for exploring the province. If you are staying strictly within the downtown Halifax core for a weekend, you can manage with walking and rideshares, but for any trip longer than two days, a rental car is essential to experience everything the province has to offer.
