After the end of the Second World War, the unique natural phenomena of this area were acknowledged permanently.
On April 8, 1949, the Plitvice Lakes were declared as a national park area and rigorous nature protection measures were established.

During the 1960s, a modern road connection to the Plitvice Lakes was constructed, which led to increasing traffic volumes.
During these years, several hotels and other objects were erected according to innovative plans of Croatian architects.
However, some buildings that would fit current standards were already demolished during the 1980s by the Communist authorities.

Between 1962 and 1968, many Western film productions of Karl May novels have been shot at the Plitvice Lakes (mainly German-French-Yugoslav cooperations).
The most successful film of this series, Treasure of the Silver Lake was also produced at some locations within the national park. (
Lake Kaluđerovac served as scenery for the Silver Lake.)

During the 1970s, detailed land registers of the national park were recorded.
The park was inscribed on the UNESCO World Natural Heritage List in 1979 in recognition of its "outstanding natural beauty, and the undisturbed production of travertine (tufa) through chemical and biological action".

During the 1980s, tourism was booming in Yugoslavia.
Plitvice Lakes National Park soon became one of Yugoslavia's most popular tourist attractions.
The beginning of the 1990s, however, marked another great turning point in the history of this national park.
In March 1991 it became the scene of the Plitvice Lakes incident (also called the "Plitvice Bloody Easter"), the first armed confrontation of the Croatian War of Independence that resulted in fatalities.
The park was held by local Serb rebels backed by Slobodan Milošević and the Yugoslav People's Army (JNA) as part of the self-proclaimed "Republic of Serbian Krajina" during the conflict and suffered some damage in the process, with hotels and other facilities being used as barracks.
During the period under the control of Serb forces loyal to Belgrade, Croats were ethnically cleansed from the region systematically.
 The region was retaken by the Croatian Army in August 1995 during Operation Storm, and the majority of the Serb population was expelled.

During the war from 1991 until 1995, many buildings in the national park were destroyed or burnt down.
Due to the apparent risk of mines, the park was even put on the UNESCO List of World Heritage in Danger during the war years.
After the war, the Plitvice Lakes were among the first areas to be cleared of mines and renovated, although some of the more remote areas in the park are suspected still to contain landmines.
In 1998, the national park was removed from the List of World Heritage in Danger.
In 2000, the national park was expanded by a further 102 square kilometres (39 sq mi) in order to protect the underground tributary streams.

Within the national park continuous scientific research projects are being carried out.
The national park administration currently endeavors to introduce new, progressive protection measures.
There is a proposal to replace the wooden bridges and paths by floating pontoon bridges.
The existing wooden paths are anchored within the travertine sediments, creating the danger of seepage and cracks of the weak travertine.

The Plitvice Lakes are today one of the most frequently visited tourist attractions in Croatia.
Due to their high natural, cultural and tourist significance, they have become a motor for the local economy.
About 1,000,000 visitors per year greatly contribute to the economic development of the wider region.

Due to high tourism and illegal construction around lakes, with faecal waste flowing down to surrounding woods and lakes without any treatment, the water in the lakes is polluted and no longer drinkable.
In its current state, UNESCO threatens to remove the park's status as a World Natural Heritage site.
