Dinara Nature Park: Sinjal Peak and Cetina River Source

Dinara Nature Park, Croatia’s youngest protected area, is a wild and untamed world of rugged mountains, karst fields, and hidden springs. Established in 2021, it spans more than 63,000 hectares across Split-Dalmatia and Šibenik-Knin counties. The park shelters Croatia’s highest summit, Sinjal, the turquoise Eye of the Earth spring at the Cetina River source, and a cultural landscape shaped by centuries of grazing and transhumance. For hikers, climbers, and nature lovers, Dinara Nature Park is a journey into the heart of the Dalmatian hinterland.

Dinara Nature Park - Croatia

Why Dinara Nature Park Matters

Croatia’s Newest Protected Area

When Dinara Nature Park was proclaimed in 2021, it became the country’s youngest nature park and the second largest by area. Its boundaries include the Dinara, Troglav, and Kamešnica mountains, the upper course of the Cetina River, and fertile karst fields where agriculture and herding still thrive. Eleven Natura 2000 sites overlap the park, underscoring its European-level ecological importance.

Sinjal: Croatia’s Roof

The jewel of Dinara is Sinjal peak, at 1,831 meters. Known simply as Dinara peak, it is the highest point in Croatia. From its summit, visitors can admire sweeping views of the Adriatic coast, the inland plateaus of Bosnia and Herzegovina, and the jagged ridges of the wider Dinaric Alps. On clear days, the panorama stretches from Velebit in the north to the distant peaks of Montenegro.

A Living Karst Landscape

The park protects more than 1,000 species of plants, including many endemics adapted to harsh limestone terrain. Endangered animals such as the Balkan meadow viper live here, along with wolves, chamois, and golden eagles. Large predators like bear and lynx occur in the wider Dinaric Alps region, but sightings inside the park itself are very rare. Human activity has shaped the environment too: centuries of shepherding carved out pastures and meadows that are now vital habitats.

Top Things to Do in Dinara Nature Park

Hike to Sinjal Peak

The most rewarding adventure is hiking to Sinjal. Two classic routes lead to the summit:

  • Glavaš trail: Begins near Kijevo and Glavaš Fortress ruins. The path ascends through rocky slopes and meadows, passing Martinova košara shelter before reaching the summit. Allow 4–5 hours of steady climbing.

  • Brezovac route: Starting near Knin, this route is longer but less steep. Many hikers stay overnight at Brezovac mountain hut before continuing to the top. The hut offers basic facilities but must be reserved in advance.

Both routes are demanding. Water sources are scarce, and the bura wind can be fierce. Good preparation is essential.

Marvel at the Cetina River Source

At the base of the Dinara lies one of the most striking springs in Europe, the Eye of the Earth. This bottomless-looking, turquoise karst spring gives birth to the Cetina River, which flows to the Adriatic at Omiš. The site is protected, and swimming is forbidden, but visitors can enjoy unforgettable views from the lookout above.

Step Into History at Knin Fortress

Knin Fortress dominates the town below and is one of Croatia’s largest and most significant fortifications. It witnessed the coronation of medieval Croatian kings and later played a role in Ottoman and Venetian conflicts. Today it is open to visitors, offering sweeping views of Dinara and the surrounding valleys.

Chase Waterfalls at Krčić

Above the Krka River source stands the Krčić Waterfall, also called Topoljski buk. This seasonal cascade tumbles from limestone cliffs, thundering in spring and after heavy rainfall, before often drying up in summer. Combined with the Krka spring below, it forms a rare karst phenomenon.

Cool Off at Peruća Lake

Peruća Lake, the third largest in Croatia, lies south of Vrlika. This reservoir, framed by mountains, is popular for kayaking, stand-up paddling, and swimming. Its calm waters and peaceful setting make it an excellent base for relaxation after exploring Dinara.

Hiking Trails and Mountain Huts

Glavaš to Sinjal

The Glavaš trail offers a direct and scenic climb. Along the way, hikers pass the medieval Glavaš Fortress ruins, grassy plateaus, and the Martinova košara shelter, a basic refuge near the ridge. The path is waymarked, but hikers should be fit and well-prepared.

Brezovac to Sinjal

This longer route begins at Brezovac mountain hut, located at 1,050 meters. Hikers often spend the night here, breaking the ascent into two days. The trail is less steep than Glavaš but covers greater distance. Brezovac is run by a mountaineering club and has 42 beds.

Other Trails

Beyond Sinjal, Dinara offers a network of paths linking ridges, valleys, and pastures. Sections of the international Via Dinarica trail cross the park, connecting it with mountains in Bosnia and Herzegovina. Hikers can also explore less demanding routes near Vrlika and Knin.

Trail Safety

Dinara is a true wilderness. Water is scarce, weather changes quickly, and bura winds are notorious. Certain remote areas still contain landmines, a legacy of war. Stick to marked trails and always check conditions before setting out.

Practical Planning

Getting There

  • By car: Dinara is best accessed by road. Knin and Vrlika are the main gateways. From Split or Šibenik, the drive takes about 1.5 hours.

  • By train: Limited services connect Split and Knin, offering a scenic but slower route.

  • By bus: Buses link Split, Šibenik, Knin, and Vrlika, though schedules may vary.

Best Time to Visit

Spring and autumn bring cooler temperatures, ideal for hiking. Wildflowers bloom in spring, while autumn offers clear views and fewer crowds. Summer is hot, with little shade, while winter often brings snow to Sinjal.

Park Rules

  • Wild camping is not allowed; use official huts or nearby accommodation.

  • Swimming at the Cetina source is prohibited.

  • Fires are strictly forbidden in summer.

  • Respect local grazing practices and avoid disturbing livestock.

Safety Considerations

Most marked trails are safe, but always follow signage. Croatia is working towards being mine-free by 2026, yet hikers should avoid wandering off paths. Carry plenty of water, food, and proper gear.

Wildlife and Nature

Flora

Dinara’s vegetation zones range from Mediterranean shrubs at lower altitudes to alpine meadows near Sinjal. In spring, orchids and other wildflowers color the slopes. Rare plants adapted to limestone thrive in the cracks of the karst.

Fauna

Dinara is home to wolves, chamois, and a variety of birds of prey such as golden eagles and peregrine falcons. The Balkan meadow viper is an iconic reptile of the grasslands. Larger predators like bears and lynx are present in the wider Dinaric Alps, but actual sightings inside Dinara Nature Park are uncommon.

Karst Wonders

Karst features define Dinara: caves, sinkholes, dolines, and disappearing rivers. The Cetina and Krka Rivers both rise here, making the park vital for regional water resources. Cavers and geologists will find countless underground passages still being explored.

Cultural and Historical Heritage

Fortresses and Ruins

The slopes of Dinara are dotted with medieval fortresses, monasteries, and villages now partly abandoned. Glavaš Fortress and Knin Fortress stand out, but smaller ruins tell stories of centuries of border conflicts and pastoral life.

Shepherding Traditions

For generations, shepherds led flocks across Dinara’s pastures. This seasonal movement, known as transhumance, shaped both the land and local culture. Stone huts, sheepfolds, and dry walls remain visible reminders of this way of life.

Local Cuisine

After a day of hiking, try traditional dishes in Knin and Vrlika. Specialties include lamb roasted under a peka (iron dome), homemade cheeses, and river trout from the Cetina. These flavors are part of the region’s identity.

Where to Stay

Knin

Knin offers hotels, guesthouses, and restaurants. Its fortress, museum, and proximity to Brezovac hut make it an ideal base for exploring northern Dinara.
