Blidinje plateau (Croatian: Blidinjska visoravan) is a karst plateau in Bosnia and Herzegovina, situated at the heart of Dinaric Alps, between major mountains of the range, Čvrsnica, Čabulja and Vran, with characteristic karstic features such as Dugo Polje field, Blidinje Lake, Grabovica and Drežnica valleys, and others.

[2] It represents important natural, hydrogeological reservation in karst of Bosnia and Herzegovina, with significant cultural and historical heritage, and Dinarides in general.

[4] A spacious plateau, 15–25 km long, is situated at an elevation of 1.150-1.300 meters a.s.l., between Čvrsnica and Vran mountains with a total area of 513 km2.

Although geomorphologically one whole, plateau is divided in two geographically and topographic distinct features, first in lower southern part, areal around the lake Blidinje, and another in northern higher part of the plateau where a flat plain Dugopolje is situated, as well as administratively between four municipalities: Jablanica, Prozor-Rama, Posušje, Tomislavgrad, and Mostar.

Going from the north and the Doljanka river, plateau opens with a flat plain of Dugo Polje at the higher end and lead toward south longitudinally between Vran at the north-northwestern side, with its highest peak on 2.074 meters a.s.l., and on the south-southeastern Čvrsnica mountain, with its highest peak Pločno at 2.228 meters a.s.l.

It is not clear how long human settlements have existed here but research began when Blidinje recently received Nature park status.

Ponor, Donje Bare, Jezero, Risovac, and Dugo Polje are five stećak medieval necropolises, named by their location.

Property spreads over seven hectares (70,000 m2; 17 acres) between the mountains of Vran and Čvrsnica and is a tourist destination as a fictional self-proclaimed micronation.

[17] The satirical idea to proclaim a republic was conceived by the Vukoja-Lastvić family who built and owns a motel on the location (Hajdučke Vrleti), consisting of the late Vinko, a tourism entrepreneur and a humorist enthusiast, as head of the family; his wife Albina; and his daughter Marija – who is the current "President of the Republic" as of March 2019.

The fictional republic was founded on the day of Diva Grabovčeva, 29 June in 2002, and is named after Mijat Tomić, who is unrelated to the owners' family, but was a historical person known as a hajduk (lit.

When Vinko Vukoja wanted to solve a problem regarding the main power supply net, he encountered years of negligence by three bordering municipalities, Posušje, Tomislavgrad and Jablanica, who couldn't agree under which jurisdiction the area fell and shifted the responsibility to one another.

Its main geological characteristic are karstic features such as Dugo Polje field, Blidinje Lake, Grabovica and Drežnica valleys, and others, with a total area of 364 km2.
