Ribnik's spring is in small town Gornji Ribnik (some 15 minutes drive from Kljuc) and is inhabited by grayling and brown trout. Ribnik is 4800m long and is very accessible for fly fishing, wide 30m, deep 50-80cm and because it is so shallow, fishermen can easily cross the river at most locations. All locations on the river Ribnik feature either FLY ONLY or CATCH & REALESE regimes.

The River Ribnik is especially rich in wild grayling, which make up 70% of the fish population. It is also rich in capital size grayling which is extremely wild and cunning. It can be caught using dry flies and nymphs - the fish are active all day on a dry fly. Ribnik generally offers experienced fishermen more than 50 actions a day, and provides a good place to learn how to fly fish.
