The Spring of the Buna

Vrelo Bune in Blagaj is one of the most beautiful and powerful karst springs in Europe, located just 12 kilometers from Mostar. The Buna River emerges from deep within a cave beneath a 200-meter-high karst cliff, releasing up to 40 cubic meters of crystal-clear, icy emerald water per second — a breathtaking sight that leaves no one indifferent. Right by the spring stands Blagaj Tekke, a dervish house from the 16th century, a perfect blend of Ottoman architecture and Herzegovinian tradition.

Legend has it that at this very spot the dervish Salih defeated a dragon that lived in the cave, and as a reward received the tekke from Duke Stjepan. By boat you can enter the cave itself and experience the spring from within, and along the river restaurants await with fresh trout and Herzegovinian specialties. The water temperature is a constant 9°C throughout the year.
