There are trains after midnight
Plenty of chauffeur service sites claim otherwise. That is false, and the official timetable for the line, version 2bis of 15 January 2026, settles it in two lines: departures from Nice-Ville towards Monaco at 00:04, 00:23, 01:05 and 01:24, and departures from Monaco towards Nice at 00:29, 00:49, 01:05 and 01:23.
We prefer the true argument, because it holds. Every one of those late services carries a day code printed on the same sheet: runs on Fridays, on Saturdays, on Sundays, from Friday to Sunday, or except Fridays and Saturdays. They exist, just not necessarily on the night you need one.
Add that a train leaves you at a station, Monaco-Monte-Carlo or Nice-Ville, and that a 01:00 return with heels and a bag does not end on the platform. The train takes about 25 minutes from Nice-Ville to Monaco. The car takes 30 minutes from one address to another, at the hour you choose, with no day code attached.
Three corniches, and the hour that decides
Twenty-two kilometres, and four ways to cover them. The Basse Corniche, D6098, hugs the coast through Villefranche-sur-Mer, Beaulieu-sur-Mer and Cap-d’Ail. The Moyenne Corniche, D6007, crosses the Villefranche pass. The Grande Corniche, D2564, runs over the Quatre-Chemins and Èze passes. The motorway completes the set, with junctions 55 Nice-est, 56 Monaco, 57 La Turbie and 58 Beausoleil.
The choice follows the hour, and it works both ways. Leaving a dinner at 23:00 is not driven like a 18:30 appointment. It is the kind of decision that never shows on an invoice and always shows in the journey time.
One useful public landmark on the Monaco side: Place d’Armes, a stop on regional line 80, which everyone can locate. It serves as a fallback meeting point when an address is hard to describe.
Four mornings when the city closes before dawn
Municipal order 2026-2563 of 5 May 2026, published in the Journal de Monaco, sets the closure times for the Formula 1 Grand Prix held from 4 to 7 June 2026: roads closed to traffic from 07:00 on Thursday and Friday, 06:30 on Saturday and 05:00 on Sunday, until the end of the sessions. The roads named are boulevard Albert Ier, place du Casino, avenue Princesse Grace, boulevard Louis II, avenue J.F. Kennedy and avenue d’Ostende.
Those hours are the only information that matters for a transfer on those days. A client with a Sunday morning flight leaves before 05:00 or leaves from a different address. We settle that with them at booking.
The rest of the year the constraint is more ordinary and just as real: the Principality has roughly a thousand on-street spaces against a network of about forty public car parks, mostly underground. You do not park outside a door in Monaco. You drop off, and you move on.
