Cerovac caves

Cerovac Caves (Cerovačke špilje) form the largest tourist-accessible cave complex in Croatia, located near the hamlet of Grab close to Gračac, on the slopes of southern Velebit at the foot of Crnopac hill, within the Velebit Nature Park.

Where exactly are the caves?

The complex sits in the Lika region, roughly 4 km from Gračac, inside the protected area of Velebit Nature Park. The parking area is at 553 m above sea level. From there, an easy 15-minute walk along a marked trail leads to the entrance of Lower Cerovac Cave (Donja Cerovačka špilja, 620 m). Reaching Upper Cerovac Cave (Gornja Cerovačka špilja, 671 m) requires an additional 10-minute uphill walk.

What will you see inside?

Two of the several caves that make up the complex are open to visitors — Lower and Upper Cerovac. Each has about 700 meters of developed passage decorated with stalactites, stalagmites, and columns. The caves are also known for significant palaeontological finds: remains of cave bears, cave lions, fossil brown bears, wild horses, red deer, and chamois have all been discovered here, making the site one of the more important fossil locations in the Balkans. The interior stays at a steady temperature of around 7°C, so a warm layer is worth packing even in summer.

How does a visit work?

Entry is only possible with a guide, as part of an organized group — the guiding fee is included in the ticket price. A tour of a single cave takes about 1.5 hours, of which 50 minutes are spent underground. Visitors who want to see both caves should plan for roughly 3 hours in total, covering two 50-minute underground visits plus the walking time between the caves and the parking lot.

When is the best time to visit?

The caves operate during the tourist season, mainly spring through early autumn, when the approach trails are dry and easy to walk. Because the cave interior keeps a constant temperature year-round, the season mostly affects the comfort of the walk to and from the entrances rather than the tour itself, since part of the trail runs across exposed mountain terrain.

Who is this attraction for?

Cerovac Caves suit nature lovers, geology enthusiasts, and travelers looking for a quieter alternative to the region's more famous show caves — visitor numbers here are noticeably lower. Keep in mind that reaching the entrances requires walking a mountain trail, which can be demanding for visitors with limited mobility.
