Krka National Park lies within Šibenik-Knin County, and covers a total area of 109 km² of the loveliest sections of the Krka River, and the lower course of the Čikola River.
The national park is a vast and primarily unaltered area of exceptional natural value, including one or more preserved or insignificantly altered ecosystems. The purpose of the park is primarily to serve science, culture, education and recreation, while tourism activities have also been introduced for its visitors.
Including the submerged part of the river at the mouth, the Krka River is 72.5 km long, making it the 22nd longest river in Croatia. It springs in the foothills of the Dinara mountain range, 2.5 km northeast of Knin. With its seven waterfalls and a total drop in altitude of 242 m, the Krka is a natural and karst phenomenon. The travertine waterfalls of the Krka River are the fundamental phenomenon of this river.
The need to legally protect the Krka River and its exceptional natural values was already recognized in the mid 20th century. The initiative to proclaim the Krka River a national park was again launched in 1971, with the drafting of a physical plan entitled Krka National Park: physical development plan. On 24 January 1985, the Parliament of the Socialist Republic of Croatia proclaimed the area covering 142 km² from the Early Croatian fortresses of Trošenj and Nečven to the Šibenik Bridge, including 3.5 km of the course of the Čikola River, a national park. Due to four urban centres (Skradin, Bilice, Raslina and Zaton), the construction of the Zagreb–Split motorway and the development of tourism and other economic activities in the area, in 1997 the Croatian Parliament revised the park boundaries by passing the Act on Amendments to the Act on the Proclamation of Krka National Park. The southern border of the park was shifted to upstream from the Skradin Bridge, and the northern part virtually all the way to Knin. The park boundaries stretch for 50 km along the upper and middle course of the Krka River (two kilometres downstream from Knin all the way to Skradin), and the lower course of the Čikola River (including the confluence and 3.5 km of the river canyon), in the territory of the towns of Knin, Drniš and Skradin, the City of Šibenik, and the municipalities of Ervenik, Kistanje and Promina.
The seat of the Public Institution of Krka National Park is in Šibenik, at Trg Ivana Pavla II 5, with branch offices in Skradin, Drniš and Knin.
Krka National Park is managed by the Public Institute, under the jurisdiction of the Ministry of Environmental and Nature Protection of the Republic of Croatia. The activities of the Institute include protection, preservation and promotion of the national park, for the purpose of protecting and conserving the natural resources, and supervising the implementation of environmental protection measures within the protected area.

Geology of the National Park
The Plitvice lakes National Park belongs to Dinaric karst area and due to its specific geology, geomorphology and hydrology it truly is one of the most impressive karst entities in the world. Apart from dolomitic rock, mesosoic limestones with dolomite inserts prevail. The ratio between less porous or water-retaining dolomites and porous Jurassic limestone sediments in the karst has influenced the landscape of the overall area today. Specific hydrology properties of rock have enabled water retention on Triassic dolomite rocks, as well as canyon formation by water cutting through Cretaceous limestone deposits. Tufa barriers are a phenomenon enabling water to remain inside the lakes.
Plitvice lake waters are supersaturated with dissolved calcium carbonate, in the form of calcium bicarbonate. As water is dispersed at a large scale at tufa barriers, it mineralises and calcium carbonate (calcite) is emitted in the form of tiny agglomerating crystals. The basic chemical formula for tufa sedimentation is the following:
Ca (HCO3)2+water dispersion → CO2+H2O+CaCO3↓ (tufa)
The invisible and at the same time essential element of this specific and complex tufa creation process are the so-called ‘blue-green algae’ (Cyanobacteria), eukaryotic algae (Diatomeae), various bacteria, Protozoa (single-cell organisms) and multi-cell microscopic organisms. These organisms represent a life community developing on rocks, plants (mosses) and submerged debris. Calcite micro-crystals are glued on mucopolysacharide mucus excreted by algae and bacteria. Crystals glued in such a way are crystal-forming agglomerate, around which calcium carbonate from water settles, helping the precipitation of well-known tufa barriers. The most prevalent moss, covering steep and vertical tufa barriers is Cratoneuron comutatum. This moss lithifies fast, and its contours remain well preserved in the tufa. At quieter places, a ‘Bryum pseudotriquetrum’ moss forms a Bryum-type tufa. The process of tufa formation dates far back into geologic history, to the conditions of warm and humid climate, similar to today. The age of active tufa barriers precipitation is estimated at 6.000 - 7.000 years, which corresponds to their formation after the latest ice age. Growth and development of tufa barriers is threatened if there are disturbances in physical, chemical and biological balance, important to the precipitation process.
