Paris on a Budget: Making Your Euros Stretch

To survive Paris on a budget, stick to the arrondissements outside the city center for housing, rely on public transit or walking, and eat your main meals at boulangeries and local markets. You can comfortably manage a trip for $130 per day if you avoid tourist-trap dining and museum passes that don't offer value.

Secure budget-friendly transport. Purchase a Navigo Découverte pass if you are staying for a week (Monday to Sunday). It costs 30 euros and offers unlimited travel on Metro, RER, and buses. Avoid individual tickets at all costs.
Optimize your dining. Do not eat at restaurants with menus in four languages. Shop at local Monoprix stores for snacks and grab 'formule' lunch deals at local boulangeries, which usually include a sandwich, drink, and dessert for 8-10 euros.
Prioritize free culture. Skip the expensive guided tours. Visit public parks like the Jardin du Luxembourg for free, and time your museum visits for the first Sunday of the month when many state museums are free to enter.
Use public water. Do not buy bottled water. Paris is filled with Wallace fountains—green, cast-iron fountains that provide free, drinkable tap water throughout the city.
