Along the Gacka River and its tributaries, there were once over 60 water mills, and nowadays there are still a few more active water mills. Experience the milling of the millstone, the murmur of the river and enjoy the old watermills.
Gacka is a river of exceptional purity, extremely rich in oxygen, which is why it is also known for its fast-growing trouts. Gacka has many smaller sources and the three largest sources: Tonković vrilo, Klanac and Majerovo vrilo.
The springs are pond-shaped, of magical color and very picturesque. Gacka is also the most famous Croatian subterranean river and the 3rd longest one in the world.
