When Newport is crowded, parking can be difficult to find. If you find a spot, mind the rules to avoid a ticket. There are parking areas at many of the mansions, the wharf area and near the cliff walk.
Be careful to feed the parking meter and watch where you park. Newport Police are very stringent in enforcing the speed limit and parking rules. We saw many a person getting ticketed for traffic violations and parking violations. We even witnessed a man's car get towed because he was parked in a tow away zone.
