Shuttle bus from Palermo to Palermo (city)
At the cruise port are a few shuttle bus options. Most cruise lines offer a shuttle bus (whether or not complimentary) to the center of the city. There is also a free shuttle bus provided by the Port Authority.
Most buses take you to Piazza Castelnuovo, a good starting point for further exploration of the city. The free shuttle bus departs at the exit of the port, opposite the docking area.
