Nežica is a stream that steals the show from many rivers thanks to its cascading waterfalls over travertine ledges – considered the most important waterfalls in the whole Kočevje region. Locally the falls are also known as the Tišenpolj waterfalls, named after a nearby village, while the stream itself is sometimes called Prifarski jarak.

The Nežica rises as a karst spring beneath the hills of Planica and Vrana stena, at an elevation of around 350 m. Its water is rich in calcium carbonate, and along its short course it builds up travertine barriers over which it tumbles in a series of waterfalls. The whole streambed is thickly coated in moss, giving the gorge a lush, almost fairytale atmosphere that's especially striking in spring and early summer when water levels are highest. The first waterfall, about 8 m high, lies near the hamlet of Grbac and forms a beautiful travertine canopy over a large cavity. Right by the main road, beneath a bridge, the second and most impressive waterfall pours down – the tallest of the group at 15 m, spreading into countless rivulets across the travertine ledge. The third waterfall is around 10 m high, after which the terrain flattens and the stream forms a series of smaller steps and pools. Further up a steeper section hides another dramatic 20 m cascade, sloping at 45° and entirely covered in travertine.

• Hamlet of Grbac, below the main Kočevje–Petrina road – easy, short approach, suitable for most visitors
• Viewpoint by the bridge on the main road – the tallest waterfall is visible almost directly from the roadside

Nežica is the most important waterfall system in the Kočevje area, and its moss-covered travertine cascades are well worth a short detour even on a quick trip through the Kostel region.
