Lore & Trivia
Ultra Dinarica traverses the Dinaric Alps — the mountain chain running down the western Balkans from Slovenia to Albania. The course crosses three countries and some of the least-visited mountain terrain in Europe: deep karst canyons, beech forest, alpine meadows, and World War II partisan trails. Balkan trail running is raw and authentic, without the polish (or the crowds) of the Alps.
