Is it possible to travel from Nice, France to Monaco in a day?
Is there any day tour from Nice to Monte Carlo?
Yes, they are very near to each other. I assume there's a train. You could check voyages-sncf.com/dynamic/_Sv...
Have a good trip.
The are frequent trains, taking about 40 minutes. If you want to fly, the helicopter service does the trip in seven minutes.
