A haven for adventurers, the valley formed by the electric turquoise advance of the Soca -- one of Europe's loveliest rivers -- is scintillating. This part of the country is blessed with gorgeous mountain views, splendid towns, plenty of well-organized sports outfitters, and a people who are as charming as they are relaxed. It may be Slovenia's least developed region, with a dwindling population of just 19,000 (generally due to overeducation!), but it is likely to provide many of the defining moments of your visit to Slovenia. Kobarid is at the heart of the more exclusive and developed portion of the valley, offering its best accommodations, and two of the country's finest restaurants. Slightly north of Kobarid, Bovec is one of the prime adventure resorts in Slovenia; it's an excellent ski resort and ideal for access to the Soca River, which hosts a number of international rafting competitions. The valley is also great for biking, with extreme cycling races held around Bovec -- and given the enchanting topography, a wonderful place to observe from the air, making paragliding particularly popular.
