"Piran is a pedestrian town." Piran Warnings Or Dangers Tip by csordila

Cars are generally not allowed in the old town. From this reason it is highly recommended to leave your car in the parking lots just outside the town and walk along the port towards Tartini Square or take one of the convenient free shuttle buses leaving the parking lots roughly every twenty minutes.
The biggest lot is along the waterfront "Parking Place Fornace" and costs about €8 per day.
If you need to drop off your bags, you can drive to Tartini Square and, if lucky, park at one of the metered spots, it's not a lot of fun since the streets are very narrow and parking costs €24 per day. Parking is free for less than 15 minutes only.
Do not park your car in spots reserved for residents or you will find the wheel of your car clamped and expect to pay a high fine to have it removed.
