Optionally, you may take bus 1 or 2 from the port to Cremaillere bus stop to transfer to bus 112 to Eze (again, only 1 euro). The latest departure from Eze back to Monte Carlo is 18:35. The train offers later return departures (more on that in a later post). Taxis between the port and Eze are approximately 40 each way.
