A large part of Grövelsjöfjällen is taken up by the Långfjället nature reserve, which surrounds Gröveldalen and is one of the largest in the country.

The highest mountain is Storvätteshågna, 1204 m above sea level and is Svealand's highest point. The Långfjäll area is part of Idre Samiby's reindeer grazing land, which means that reindeer are common here in summer.

Patches of pure primeval forest with no traces of felling can be found in the area. Commonly occurring birds are black grouse, heather piping plover, meadow lark and sandpiper on the mountain heath, grebe on the moor and shrike in the forest. Along the waterways, the small starling is common. You can also come across moose, fox, marten and bear.

Fishing has a long history in the area. The availability of fish in lakes and streams is good. Trout, char, grayling, whitefish, perch, pike are common species. With the Dala Fiskefjällkort, you can fish in all waters within the Långfjället reserve, with the exception of Storån's quota fly fishing and some private waters.
