The Wyżni Chochołowski Potok is considered the source of the Czarny Dunajec river.

[1][2] The Czarny Dunajec flows through Podhale, initially to the north-west, between Pogórze Gubałowskie and Orawicko-Witowskie Wierchy, then north through the Orava-Nowy Targ Basin.

The water depth is variable; from shallows to plunge pools up to 3 metres (9.8 ft) deep.

[5] Fly fishing is allowed along the entire length of the river, but only outside the buffer zone of the Tatra National Park (below the mouth of the Iwański Potok).

The Czarny Dunajec mainly contains brown trout, less common grayling and chub.
