This is one of the longer, flatter, seamless running opportunities in the Dubrovnik area. A waterside road, the Ul. na Rivi, runs along the north side of the river, which lets out into the Adriatic. It’s 6.7 km (4.1 mikes) out and back, from Rožat to Stara Mokošica (Old Mokosica). The road is not car free, but traffic is not bad since the main road runs just north. There are great views of the water, mountains, and Dubrovnik the whole way. Rožat is about 8 km northeast of Dubrovnik.
