The hook
The most visited city on earth, and still worth it: the Louvre and the Seine and the boulevards, yes, but also a city of twenty villages where the actual pleasure is walking until you find a café you like and sitting in it.
01Why it's worth it
Paris is not underrated and never will be, which is exactly the trap. The headline sights are genuinely great, the Louvre, the Musée d'Orsay's impressionists, Notre-Dame reopened after the fire, the Rodin garden, Sainte-Chapelle's glass, and they are also crowded, ticketed, and often the least interesting hour of your day. The city's real character lives in its arrondissements: the canal-side evenings on the Saint-Martin, the hill villages of Belleville and Ménilmontant with their street art and immigrant food, the covered passages, the Marais, the markets, the bouquinistes, the parks where Parisians actually spend Sunday. Add the food, which ranges from three-star temples to a two-euro baguette that shames most countries' best bread. Go with a short list and a lot of unscheduled walking; that's the version people fall for.
02How to experience it
Book two or three big museums in advance and take them early, then spend the rest on foot: Canal Saint-Martin, Belleville, the Marais, Montmartre before nine, the Coulée verte. Eat at neighbourhood bistros away from the monuments, picnic in the parks, and take the métro rather than fighting the surface. Spring and autumn are kindest; late summer is hot and half the city is away.
From the locals
Regulars there give the same two-part advice. On the myth of secret Paris: "Paris is the most visited city in the world, there aren't really 'hidden gems.' The best strategy would be to walk around and go in whatever direction looks prettiest." And on where to point that walk: "tourists tend to focus on the most obvious parts… but Paris has many interesting sides outside of those, like walking along the Canal Saint-Martin, discovering Belleville and Ménilmontant."
