We did not go on an organized tour. Monte Carlo is a small town. Very clean and beautiful. As the Queen Mary couldn't dock in the port they supplied tenders, these were fast and efficient. One can walk around the town in less than a day. We took a little red and white train for 8 euros return, this goes from outside the Ocean museum which is reached by walking up to the top of the hill. Lots of stairs to climb though. This little train goes right round Monte Carlo, through all the main streets and is a good cheap way to see the main areas, there is a guide (through headphones). Once the train took as back be then walked back down the steep hill into the port and right round to the famous casino and back to the port. A fabulous day in a beautiful town.
