Porto Mirabello is a spanking new and very upmarket marina situated in the Porto Mercantile (commercial harbour) of La Spezia. The marina has been constructed on an artificial island between the naval harbour and the commercial docks and provides a total of nearly 500 berths, including for superyachts up to 100 metres. As might be expected from a marina pitched at superyachts, the standard of the facilities here is extremely high, as are the prices.
