Port de la Condamine, the main harbor basin, lies N of the town of Monaco. It is entered between two breakwaters which form an entrance 100m wide at the surface and 80m wide at the bottom. Depths up to 22m lie in the outer part of this basin and the quays have depths of 4 to 8.5m alongside. Vessels up to 135m in length, 20m beam, and 7m draft can be accommodated. The harbor is mainly used by pleasure craft and there is very little commercial activity.
