Primorska is a historic region in western Slovenia, bordering Italy near Trieste. The region lies between the Julian Alps, the Adriatic Sea, and Istria. It is known for its beautiful coastline, impressive Julian Alps, and unique Karst Plateau.
Fishing and tourism in the coastal area, with the well-known coastal towns of Koper, Izola, and Piran, are Primorska's main sources of income. Winemaking is renowned around the Brda Valley. Agriculture and livestock farming also play an important role, with the perfect climate for growing crops and raising livestock.
The karst underworld is among the most extraordinary phenomena that nature has to offer: from gorges with raging rivers to stalactites in all sorts of bizarre shapes, with the highlights being the famous Postojna Caves and the lesser-known, but breathtakingly beautiful Škocjan Caves.
In the mountains surrounding the Soca River, nature is at its finest, with beautiful views and outdoor activities on the river and in the rugged mountains. People are drawn here by the diverse natural beauty and rich cultural heritage. Because the mountainous border region is difficult to access, forts and castles were built in the past for protection and security. You'll still find many traces of the fighting here, such as the Alpine Wall, the Rapallo border, and the Isonzo front from World War I, especially around Kobarid.

In this region, four routes have been established that visit the various areas of Primorska. Because there is so much variety in this region of Slovenia, the routes each have their own unique accent.
