Piva Canyon Road is a very scenic drive, part of the European route E 762, in the southwest of Montenegro near the border with Bosnia and Herzegovina.
The road is asphalted and still remains an adrenaline-pumping journey, following the Piva Canyon, cut between the mountains of Bioč, Volujak, Maglić and Pivska planina. The road's winding design, providing stunning panoramic views, is very curvy and fun for a leisurely ride, so it pays to take it slow. The canyon is 33 km long, deep up to 1.200 m, in the Piva, one of few most spectacular rivers in Montenegro. The road goes through many rocky tunnels through the rocks of the canyon, near the lake. The views are superb and the place remote, but you have to keep your eye on the road and the other drivers! The asphalted road, also known as M18, runs along the Lake Piva reservoir, the second largest lake in Montenegro. It’s the result of the construction of the Mratinje Dam on the Piva River in 1975. The dam is 220m (720 ft) high, and therefore one of the highest in Europe and the view from the top is astonishing.
Stay away if you're scared of heights. Drive carefully: high risk of landslides. The road alongside the river is a feat of engineering in itself, clinging to the cliffs and passing through 56 small and unlit tunnels carved out of the stone.
