Via Ferrata Vulin Potok is located in a picturesque canyon above Blagaj and leads all the way to the medieval Stjepan Grad Fortress, one of the most famous historical landmarks in Herzegovina. The ferrata follows the bed of a seasonal stream through a narrow canyon surrounded by high cliffs, offering a unique blend of nature, adventure, and history. Although it is often described as an easy ferrata, some sections require more attention and experience due to steeper and more exposed passages. During the ascent, visitors pass through an impressive canyon, and at the end they are rewarded with beautiful views of Blagaj, the Buna River valley, and the surrounding Herzegovinian mountains. The visit can be rounded off with a tour of Stjepan Grad Fortress and the famous Vrelo Bune.
