Many of the city's attractions are east of the fortification walls in Vieux-Québec (Old Quebec). This area has a distinct European feel that is unique in North America with its stone buildings and winding streets lined with shops and restaurants. Porte St-Louis (St. Louis Gate) and Porte St-Jean (St. Jean Gate) are the main gates through the walls from the modern section of downtown. West of the walls are the Colline-Parlementaire (Parliament Hill) district and the Plaines d'Abraham (Plains of Abraham).

Quebec City's skyline is dominated by the massive Château Frontenac Hotel, perched on top of Cap-Diamant. The hotel is beside the Terrasse Dufferin (Dufferin Terrace), a walkway along the edge of the cliff, offering beautiful views of the Saint Lawrence River.

Near the Château Frontenac is Notre-Dame de Québec Cathedral, mother church of the Roman Catholic Archdiocese of Quebec. It is the first church in the New World to be raised to a basilica and is the primatial church of Canada.

The Terrasse Dufferin leads toward the nearby Plains of Abraham, site of the battle in which the British took Quebec from France, and the Citadel of Quebec, a Canadian Forces installation and the federal vice-regal secondary residence. The National Assembly, Quebec's provincial legislature, is also near the Citadelle.

The Haute-Ville (Upper Town) is linked by the Escalier «casse-cou» (literally "neck-breaker" steps) and the Old Quebec Funicular to the Basse-Ville (Lower Town), which includes such sites as the ancient Notre Dame des Victoires church, the historic Petit Champlain district, the port, and the Musée de la Civilisation (Museum of Civilization). Laval University is located in the western end of the city, in the borough of Sainte-Foy. However, Laval University's school of architecture is located in Vieux Quebec. The central campus of the Université du Québec is also located in Quebec City. Canon balls are placed beside "Château Frontenac."

Quebec City is known for its Winter Carnival and for its Saint-Jean-Baptiste Day celebrations.

Tourist attractions located near Quebec City include Montmorency Falls and the Basilica of Sainte-Anne-de-Beaupré.
