Operating temperature in the Cave Park Grabovača has reach its maximum. The beginning of July has been marked with increased influx of visitors as well as volunteers from the whole Europe. Scouts from Belgium are currently assisting employees in the park with cleaning the coast of the river Lika. Volunteers from France came to the park as part of a European Union project Karst 4U: Discover undiscovered. Ten of them will stay in Perušić during the next month. As a part of the project there will also be a French language course which will start on July 10, 2015 for 20 participants.
