This is a guide to the best places to run in Portorož and the neighboring Slovenian seaside resort towns of Piran, Strunjan, and Izola. They’re located on the Istrian peninsula on the Gulf of Trieste at the northernmost point of the Adriatic Sea. From Portorož, there’s a great waterfront path north to Piran, or paths headed south around the marina and then along the Jemeja Canal. Another great run near there on paths around the Krajinski Park Salt Flats. In Strunjan, the route includes the harbour, salt flats, and more rugged Park Strunjan. And just east in Izola, there’s nice running around the marina and a path headed south, or a multi-use path along the water east to Koper.
