Due to its lush green colour, the Soča, one of Slovenia's most beautiful and cleanest rivers, has been referred to as "the emerald river".
It is renowned worldwide not only for its unique beauty but also for its white water rapids offering some of the best adrenaline-pumping water sports experiences in this part of Europe, including rafting, kayaking and canyoning.
The Soča river has its source in Trenta, a scenic alpine valley renowned for some of the country's most beautiful landscapes. The Trenta Museum offers an insight into the unique cultural and natural features of the area, parts of which are incorporated into the Triglav National Park. Several high-altitude ski resorts are located close by.
The valley's numerous beauties and attractions worth visiting notably include the world renowned World War I Museum in Kobarid and the Kozjak waterfall, famous for an underground chamber with a pool of emerald water.
