The Vilsalpsee mountains (Vilsalpseeberge) are located in the northeast of the Allgäu Alps between the Oberjoch and Notländ saddles. They are bounded by the Tannheim, Lech, Tyrolean Schwarzwasser and Ostrach valleys. The highest peak is the Leilachspitze, 2,274 m, and main dolomite is the predominant rock. The lake of Vilsalpsee, accessible from the Tannheim valley, lies in the middle of the subgroup. In the literature, this sub-range is sometimes also counted as part of the Tannheim Mountains. Mountain paths pass through the range, but many summits are hardly visited. They may be climbed by experiences mountain walkers without too much difficulty despite the lack of trails to their summits.
