On foot
Monaco is about 2 km² and walkable end to end. The constraint is vertical, not horizontal.
The Principality maintains a network of public lifts, escalators and travelators precisely because of the gradients. Official figures for how many differ, so the guide describes the network rather than counting it.
Bus
The Compagnie des Autobus de Monaco runs the Principality’s bus network.
A dense regular network plus express and on-demand services across the districts, running biofuel and electric vehicles.
Boat bus
Line B of the urban network is a solar-electric boat across Port Hercule.
It crosses between Quai Antoine 1ᵉʳ and Quai des États-Unis in both directions — a shortcut on foot-days between the Rock and Monte-Carlo.
MonaBike
Electric bike hire from 49 stations around the Principality.
Government-authorised on-demand electric bicycles.
Taxi
Monaco operates an official taxi service with flat-rate fares.
Used for journeys inside Monaco and between the Principality and Nice airport.
