Izvir Nadiže (Nadiža spring) is an exceptional karst spring in the Tamar valley in the Julian Alps. The catchment area is Mount Zadnja Ponca. It emerges from a water filled karst cave at the foot of a limestone cliff. Then it immediately falls over a 12 m high waterfall. The Tamar river is only 300 m long, on this distance the brook is quite steep with many rapids, and at the end the water is completely swallowed by a ponor. The swallow hole is at an altitude of 1,110 m asl, 122 m deeper than the spring.

The water of Tamar river flows to the Planina plain which is covered by gravel. The water sinks quite unspectacular into the gravel. This spring is the actual spring of the Sava Dolinka river, the water reappears on the other side of the mountain in the Zelenci spring.

The shortest way to reach the Tamar river is by car from Kranjska Gora south to Planica, 5,3 km. Here is the lodge Planinski dom Tamar, close to the sink. From here its a 30 minutes walk on a trail along the river to the waterfall. The last part along the waterfall to the spring requires climbing, we strongly recommend appropriate shoes and a helmet.
