Apart from the Iron Gates Gorge, the geopark includes parts of the Miroč and Kučaj mountain massifs, with total area of 1,330 km2 (510 sq mi).

Panoramic view includes mountains of Deli Jovan and Veliki Krš in Serbia and the Carpathians in Romania.

Viewpoint Greben was named by Jovan Žujović as the "most beautiful hill in the Balkans" at the 1900 Geology congress in Budapest.

The river forms several cascades in the heavily forested area before creating the Blederija waterfall, 8 m (26 ft) tall.

Surrounding area is rich in animal life, especially deer and wild boar, and there are two protected hunting grounds in the vicinity, Vratna and Ploče.

The area is today heavily forested and scarcely populated, but in the Roman period, the legionaries built a road through this valley, as a shortcut between the locations where the modern towns of Donji Milanovac and Brza Palanka are.

[5] The territory of the national park is filled with a series of other important features: abundant and diversified animal and especially plant life, attractive surroundings and landscapes, cultural and historical monuments and other anthropogenic tourist attractions, including a 253 km2 (98 sq mi)[7][8][9] artificial Lake Đerdap, the largest lake in Serbia, formed by the construction of an Iron Gate I Hydroelectric Power Station (or "Đerdap").

It wouldn't be a classical power plant with another dam, but was planned to use the hydro-electrical potential of the already existing Lake Đerdap.

The reversible hydro plant was projected in the vicinity of Donji Milanovac, on the park territory in the Pesače section.

Some preparatory works have been done in the 1970s on the location of Debelo Brdo, upstream of the mouth of the Boljetinska reka into the lake, but the idea was abandoned due to the worsening of the economic situation in Yugoslavia in the late 1970s and the power plant was never built.

During the dry or winter periods, Đerdap II would work as the classical hydro plant but using only stored waters which would fall for 400 m (1,300 ft) onto the turbines.

Internationally protected are floating fern, Fritillaria degeniana, water caltrop, Bulbophyllum loroglossum and cat grass.

Other spotted birds include European roller, woodchat shrike, booted eagle, common tern and greylag goose.

Lepenski Vir is the 11,500-year-old archaeological site with exceptionally important traces of settlements and the life of the Mesolithic and later Neolithic people.

Major medieval monument is the Golubac fortress with numerous artifacts discovered in it: pottery, iron tools, hatchets, pickaxes, spears, bolts, etc.

Two of the most popular include the one about the devil face's midget with goat ears and legs, long white beard and the conical hat.

The wetlands developed after the artificial lake was created, which elevated the underground waters also, causing frequent flooding of the surrounding area.

[11] Đerdap National Park has become one of the most visited tourist regions in Serbia especially after the construction of the dam and the formation of the large lake.
