The canyon is cut between the mountains of Bioč, Volujak, Maglić and Pivska planina, its 33 km long, deep up to 1.200 m and river generates immense power used for the power station of Mratinje (342 MW) which dammed the canyon in 1975. The dam is 220 m high, one of the highest in Europe and creates Lake Piva, third largest in Serbia and Montenegro (12,5 km², altitude 675 m, 188 m deep), which flooded the old location of the monastery of Piva from the 16th century, so the monastery was moved to the new one.
The canyon Nevidio is considered to be the most impassable Canyon in Europe. It was completely impassable except for professionals with alpinist and diving skills, but today Nevidio is available for enthusiasts and tourists willing to take challenging adventure.
“Treasury of Nature” title is without doubt the right tributary of the Mrtvica Canyon. The canyon of the river Mrtvica seems astonishing, almost terrifying in its wild beauty. It is unexplored and unknown partly (for those who enjoy in nature there is marked way). It abounds in vegetation, typical for deep canyon there are remains of ecosystems of the rainforest.
Morača is one of most beautiful river canyons in Montenegro which separate the Moracke mountain range from the Sinjajevina range. It originates in northern Montenegro, under Rzača mountain. It generally flows southwards for some 113 km (70 mi), before emptying into the Skadarsko Jezero. In its northern part, the Morača is a fast mountain river, and has cut a canyon north of Podgorica.
The Tara Canyon, also known as the Tara River Gorge, is the longest canyon in Montenegro. It is 82 kilometers (50 mi) long and is 1,300 meters(4265 feet) at its deepest, making it the deepest river canyon in Europe. The canyon is protected as a part of Durmitor National Park and is a tentative UNESCO World Heritage Site. The Tara River cuts through the canyon. The Tara River, at its end making confluence with piva, becomes the Drina, and is some hundred and fifty kilometres long. In its passage through the Tara National Park, the river has a mean fall of 3.6 metres/kilometre, making a host of waterfalls and cascades possible, thus creating with its uniqueness The Montenegrian Colorado.
A scene so magnificent and so impressive that it is worth all the journey from England just to have looked at it.
All along its flow, the Tara gets large quantities of water from numerous sources, and quite a few tributaries. The most important tributaries on the left bank of the Tara are Ljutica and Susica, and the most important tributaries on the right bank being Vaskovaska rijeka and Draga. The most important source is the source Bajlovica sige, a source placed on the left bank of the Tara river giving to the Tara a few hundred litres per second, where the water sourcing from the Bucevica cave falls into the Tara more than thirty metres high, and more than a hundred and fifty metres wide.
Very special are the Tara cascades. The roar from the cascades is heard on the very peaks of the canyon. There are more than forty cascades, the most famous being: Djavolje lazi, Sokolovina, Bijeli kamen, Gornji tepacki buk, Donji tepacki buk etc. Because of the quality of its water, and because of its unique ecological system, Tara in 1977 was put into the programme “Covjek i biosfera” (People and Biosphere) and inscribed into the ecological biosphere reservations of the World, being thus protected under an internationally issued convention. There are rocky and pebbly terraces, sandy beaches, high cliffs, and more than 80 large caves along the canyon.
