The montane zones are relatively rare in the park, as its upper limit is about below most altitudes in these northern latitudes. The flora of this zone is constituted by old-growth forests of conifers, with mainly Scots pines and including Norway spruces. The pines can become very tall, particularly those around Lake Rittak, in the south part of the park. The undergrowth is mostly covered with mosses and lichens, in particular reindeer lichen, and also with "Vaccinium myrtillus", "Empetrum nigrum" and cowberry.
