The principality is a country without an airport. Overseas visitors must fly to Nice, France, then transfer to Monaco by bus, car, taxi, or helicopter. From points within Europe, the French rail system stops at the Monaco Monte Carlo station several times every hour.

Monaco is less than 1 square mile, with only 2.5 kilometers (about a mile and a half) of coastline, so you can walk everywhere, even to France. Facing the Mediterranean, the principality lies exactly where the Alps fall into the sea, making for steep hikes from the shore to the hills above. As an alternative, there are over public 30 elevators, often hidden in parking lots, to ease the pain of the climb. Compagnie des Autobus de Monaco has a 5€ day pass that allows visitors unlimited use of its five bus lines and its solar electric boat service across the Port Hercule.
