Driving the canyon
26 km from Plužine to Šćepan Polje, through 57 tunnels and across the Mratinje Dam.

A road through 57 tunnels, Mratinje Dam and Lake Piva
The Piva river has cut a canyon 33 kilometres long and up to 1,200 metres deep between the Bioč, Volujak, Maglić and Pivska Planina mountains.
In 1975 the 220-metre Mratinje Dam closed the canyon and created Lake Piva, so most of the canyon is now driven high above turquoise water. The road from Plužine to Šćepan Polje, built in the 1970s for the hydroelectric plant, runs through 57 tunnels cut into the rock, across the top of the dam and on along the river to where the Piva joins the Tara to form the Drina.
Highlights

Between Plužine and Šćepan Polje, over 26 kilometres, the road passes through 57 tunnels totalling about 5.7 km. It was built in the 1970s for the Piva hydroelectric plant and cut into the canyon walls: the tunnels are short, narrow and mostly unlit, and in one of them the road even forks towards the village of Duži. The drive needs care, but the whole stretch is one long viewpoint.

Completed in 1975, the concrete arch dam is 220 metres high and one of the highest in Europe. Its crest is 268 metres long, and about 820,000 m³ of concrete went into it. The road runs across the crest itself: the lake on one side, a drop to the Piva riverbed on the other. There is nowhere to stop on the dam, but just past it and a short tunnel there is a lay-by where you can park.

The dam flooded most of the canyon and created Lake Piva: 12.5 km² in area, about 45 km long and up to 188 metres deep, at 675 m above sea level. The turquoise water between steep cliffs is in view almost all the way from Plužine to the dam. The old settlement of Plužine lies at the bottom of the lake.

Downstream of the dam the Piva flows freely again, north through a narrow canyon. The road drops along the river through more tunnels, and in places the walls close in so tightly that the canyon feels like a gorge from the car. You can stop at lay-bys along the road to look down at the river.

At Šćepan Polje, on the border with Bosnia and Herzegovina, the Piva joins the Tara and together they form the Drina. There is a border crossing here too, so the canyon road is often driven by people heading to Foča and Sarajevo or entering Montenegro from that side.

The 16th-century Piva Monastery stood on a site later flooded by the lake. Between 1969 and 1982 it was moved stone by stone, frescoes included, about 3.5 km away to safer ground. It is only a few kilometres from Plužine and easy to combine with a drive through the canyon.
