Where do small cruise ships dock in Monte Carlo? Can you explore the town on foot? What are the best places to visit?

Monte Carlo is one of five sectors within Monaco and smaller cruise ships dock right in its famous harbour, which in itself is one of the must-sees when visiting the town. Monte Carlo is small and easily explorable on foot and the best places to visit aside from the harbour are the famous casino with its beautiful interiors; the lively Casino Square, which is great for people and car watching, the impressive Opera House and to get away from the hustle-bustle, the Japanese Gardens.
