Veliko jezero, lake in Croatia

Veliko jezero is a lake in Lika-Senj County, Croatia, within the karst plateau near the village of Vrhovine. Its basin lies in a limestone depression, with steep rocky slopes on the northern side and gentler forested banks elsewhere. The water is deep and clear, and the lake is fed by underground springs.

Veliko jezero lies in the Plitvice Lakes system, within Lika-Senj County. The lake is part of a chain of karst lakes formed where water rich in dissolved limestone deposits travertine barriers, which dam the valley and create the stepped basins. Its name, meaning "Great Lake" in Croatian, marks it as the largest of the Plitvice lakes by surface area. The lake sits at the lower end of the upper lakes cluster, near the Prošćansko area.

Access to the lake comes via forest paths and rural roads from nearby villages, reachable on foot or by vehicle depending on starting point. There is little tourist infrastructure here, so visitors should come prepared for a natural setting and check conditions before swimming or exploring.
