evidence: Piran is situated at the tip of the Piran peninsula on the Gulf of Piran. It borders Croatia to the south, and the municipalities of Izola and Koper to the east and faces Italy across the Gulf of Trieste and the Adriatic Sea. With Piran closed off to traffic except for the residents, the best way to see Piran is on foot. Start out by visiting the many beautiful buildings in Piran and then hike the many footpaths around the city.
