Koštak

Koštak is a hill rising above the village of Konjsko in the Klis municipality, Split-Dalmatia County, Croatia. Standing at roughly 637 metres above sea level, it sits just north of the Kozjak cliffs and towers directly over the wide Konjsko field, giving anyone who reaches the top a view that stretches across the inland countryside and out toward a stretch of the central Adriatic Sea.

What makes Koštak worth a visit?

Koštak's summit is not just a scenic lookout — it is a registered archaeological site. The remains of a prehistoric hillfort, known locally as a gradina, still crown the top of the hill, evidence of an Illyrian fortified settlement built long before Roman times. Communities in this region typically chose hilltops like this one precisely because they offered wide visual control over the surrounding land. From Koštak, it was possible to watch both the inland routes leading through the valley and the approaches from the coast, which made the hill a strategically valuable position for whoever controlled it.

How do you get to Koštak?

The hill lies right next to Konjsko, a small village that belongs to the Klis municipality, a short drive from Split. Konjsko itself has a long documented history: it first appears in a 1083 charter issued by King Zvonimir, who granted the land to the Archbishop of Split. The village fell under Ottoman control before the nearby fortress of Klis was captured in 1537, and it was not liberated until 1685. In 1530, the Ottomans built a square fortress, or kula, in Konjsko, with a large walled courtyard reportedly able to hold up to a thousand horses — a tangible reminder of the region's turbulent frontier past.

What will you see once you're there?

Visitors coming to Koštak should expect a quiet, low-key walk up a hill with visible traces of an old fortification and a panorama that combines the rocky backdrop of Kozjak with distant sea views. This is a destination for people interested in the archaeology and history of the Klis area rather than a fully developed tourist site — there are no facilities on top, so come prepared for a walk on natural, unmarked terrain.

When is the best time to go?

Spring and autumn are the most comfortable seasons, since the exposed, rocky hill gets considerably hotter in midsummer and visibility toward the Adriatic tends to be at its best outside the peak heat. In summer, an early morning or late afternoon visit is advisable, as there is little shade along the way up.
