With a total distance of 740 km, Danube Ultra is the longest tourist cycling route in Bulgaria. It connects the country's most north-western settlement, the village of Kudelin (Bregovo municipality) with the most north-eastern settlement, the village of Durankulak on the Black Sea. From Vidin to Silistra, the trajectory of the route overlaps the Eurovelo 6 transcontinental route. Danube Ultra is the winner of the Grand Prize "Innovation of the Year in Tourism" of the Ministry of Tourism of the Republic of Bulgaria.
