The Best Travel App for Paris

Paris has 14 Métro lines, 4 RER regional lines, and an extensive bus network — all converging on a city where almost every major attraction is within a short walk of a station. The challenge for tourists isn't finding a station; it's knowing which line, which direction, and how to transfer without losing time.

Why CityNav Is the Best Travel App for Paris

📡
All 14 Métro lines + RER offline

✈️
RER B to CDG airport — covered offline

The RER B runs from Charles de Gaulle Airport to central Paris in 45 minutes for around €12. CityNav maps the full route so you can navigate from the airport to your hotel without needing to buy a local SIM on arrival.

🗺️
AR walking to the Eiffel Tower and beyond

Point your camera at street level and AR arrows guide you directly to the Eiffel Tower (from Bir-Hakeim), the Louvre (from Palais Royal–Musée du Louvre) or any other landmark — no map rotation required on Paris's irregular street grid.

💳
Navigo Découverte weekly pass guidance
