What makes Paris worth visiting
Paris concentrates its reasons to visit along a few kilometres of the Seine, whose banks are listed as World Heritage. The city proper is compact, twenty arrondissements spiralling out from the Louvre, and most of what visitors come for sits within a walkable band on either side of the river, from the medieval island core to the grand boulevards.
Neighbourhoods to know
The Île de la Cité is where the city began, with Notre-Dame and Sainte-Chapelle. The Marais keeps its pre-revolutionary streets and many of the free city museums, the Latin Quarter and Saint-Germain hold the Sorbonne, the Panthéon and the Luxembourg Gardens, and Montmartre remains a hilltop village around Sacré-Cœur. The 7th arrondissement gathers the Eiffel Tower, the Musée d'Orsay and the Musée Rodin.
When to go and for how long
April to June and September to October bring mild weather and manageable lines, while July and August are the hottest and busiest months. Winter stays quiet outside the holidays. Three to four full days cover the main sights: one for the islands and the Louvre, one for the Eiffel Tower and the Left Bank museums, one for Montmartre, and a fourth for Versailles.
Getting around
The centre rewards walking, and the métro reaches everything else with stations rarely more than a few minutes apart. RER B trains link Charles de Gaulle airport with the centre, métro line 14 runs from Orly, and the RER C follows the Left Bank towards Versailles.
