Many of the rivers that flow into the River Muoniojoki have their source on the fell tundra or at the area's lakes and mires. The largest of these tributaries are the Rivers Tarvantojoki and Harrijoki. There are plenty of new catches for avid fishers, who are looking for new challenges.
There are plenty of rivers in Tarvantovaara Wilderness Area, which are in their natural state and have a diverse array of fish in them. The most common catches are the Grayling (Thymallus thymallus) and the Whitefish (Goregonus lavaretus), but Trout (Salmo trutta) is also quite common at some spots. The fishing waters in the area are most easily accessible in the winter, as the area's extensive marshlands make movement difficult in the summer.

Hook-and-line fishing and ice fishing are allowed under everyman's rights, except where specific restrictions apply. In the still waters of the wilderness area, hook-and-line fishing and ice fishing are permitted free of charge with one rod.
