Mers-les-Bains
Half a day to a full day: walk the Belle Époque seafront, climb to the Notre-Dame de la Falaise statue, then cross the bridge to Le Tréport for lunch.
Mers-les-Bains is a small Belle Époque seaside resort on the southern Hauts-de-France coast, just 2.5 hours from Paris by train. Its main draw is the promenade lined with colourful early-20th-century villas and the white chalk cliffs that frame the beach. Most visitors combine it with neighbouring Le Tréport and Eu, making it a half-day or single-night stop rather than a base.

Rules in force · 8Non-EU visitors get 90 days in any rolling 180-day window…
- Europe ↗Non-EU visitors get 90 days in any rolling 180-day window, counted across all 29 Schengen states together — not per country; the Entry/Exit System now logs each crossing, so an overstay is detected automatically.
- Europe ↗On the first Schengen entry since EES began, non-EU travellers give four fingerprints and a face photo at the border instead of a passport stamp; there is nothing to apply for or pay in advance.
- France and Monaco ↗France has run temporary identity checks at its internal Schengen land borders since 2015; carry a passport or EU/EEA national ID on trains and buses from Italy, Spain, Belgium, Germany, Switzerland and Luxembourg.
- France and Monaco ↗Nights in France and Monaco draw on the same Schengen 90-in-180-day allowance as the rest of the area; Monaco does not reset or pause it.
- France ↗France is in the Schengen area. Check the entry rules for your passport on official sources; the EU's Entry/Exit System registers non-EU visitors' fingerprints and photo at the first Schengen border, and further pre-travel authorisation rules are being introduced.
- France ↗TGV (including the low-cost Ouigo) and Intercités night trains need a seat reservation: a rail pass alone does not let you board.
- France ↗Paris, Lyon and other large cities run low-emission zones that require a Crit'Air sticker on cars; check before you drive a hire car or your own car into a city.
- France ↗Carry your passport or national ID card: police can ask for identification, and hotels register foreign guests.
Entry rules depend on your passport. Full visa guide
