Rules in force · 10Non-EU visitors get 90 days in any rolling 180-day window…Streets between the harbour, the Rock and Monte-Carlo are…
- 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.
- Monaco ↗Monaco is not in the EU but is inside the Schengen area in practice through France: the French entry rules for your passport apply, and there are no border checks from France.
- Monaco ↗The Monte-Carlo Casino gaming rooms admit adults only with a passport or ID; Monaco citizens may not gamble there, and dress rules apply in the evening.
- Monaco ↗Do not walk around the town bare-chested or in swimwear away from the beach: local rules forbid it.
- Monte-Carlo ↗Plan every leg along the coast by regional train or bus; avoid the Grand Prix days when trains and roads are full.
- Monaco city ↗Streets between the harbour, the Rock and Monte-Carlo are steep: large suitcases go from the car to the door, never on a walk between districts.
- Monaco city ↗During Grand Prix week (late May or early June) streets close for the circuit and hotels on the whole coast fill; plan another date or a base in Nice with an early train.
