Paris has a reputation for being an expensive city, but visiting the capital without spending a fortune is entirely possible. Between the free permanent collections at city museums, large parks open to everyone, and neighborhoods that reward walking just as much as a paid guided tour, a few simple habits go a long way toward keeping your trip affordable.

Housed in two historic mansions in the Marais, the Musée Carnavalet traces the entire history of Paris through its permanent collections, which are free to visit for everyone. It is one of the best examples of the city's municipal museums, whose permanent collections never charge for entry.

This large park in the 6th arrondissement, like most public gardens in Paris, is free to enter from sunrise to sunset. Its lawns, ponds and hundreds of green metal chairs make it a perfect spot for a picnic or a quiet break, without spending a cent.

The rooftop of Galeries Lafayette Haussmann is free to access and offers one of the best views over Paris, taking in the Eiffel Tower, the Opéra Garnier and the city's zinc rooftops. It makes a perfect free alternative to paid observation decks like the Eiffel Tower or the Tour Montparnasse.

The metro, buses and RER trains reach every corner of Paris for a fixed fare, far cheaper than a taxi or a private ride-hailing car. For a multi-day stay, a transport pass caps your spending and lets you hop on and off without counting every trip.
A sandwich or a slice of quiche from a bakery, topped off with fruit or cheese from a neighborhood market, costs a fraction of a restaurant meal. Eating along a canal, in a square or on the steps of a monument is also part of the Parisian experience.
Beyond Carnavalet, the permanent collections of several city museums, such as the Petit Palais, are free year round, while only their temporary exhibitions charge for entry. In national museums and monuments, visitors under 26 who are EU residents also get in for free, and some venues additionally offer free admission on the first Sunday of the month.
The Marais, the Latin Quarter and Montmartre all reward simple wandering, no guided tour required. Following a street at random, stepping into a courtyard or pausing in front of an old shopfront costs nothing more than a comfortable pair of shoes.
Paris has more than a hundred Wallace fountains, the green cast-iron drinking fountains installed across the city since 1872, which provide free drinking water. Filling a bottle at one instead of buying a new one at every stop adds up to real savings over several days.
As in any major tourist capital, it pays to stay alert on the metro and around major monuments (Sacré-Cœur, the Eiffel Tower, the Champs-Élysées), where street hawkers and pickpockets tend to target distracted visitors. Always buy monument tickets through official websites or on site, never from a street seller or someone approaching you in a queue.
