The three main rivers leading to this lake are the Seez, Murgbach, and Linth. The latter continues its course from Walensee to Lake Zurich. The Schnittlauchinsel, located at the eastern end of the lake, is the only island in the Walensee.
The Churfirsten range raises steeply on the north side from the lake's level at 419 m to 2,306 m above sea level. On the south, the lake is overlooked by the massif of the Mürtschenstock, culminating at 2,441 m. The highest point of the lake's drainage basin is the Tödi (3,614 m).
The lake provided the inspiration for a solo piano piece by Hungarian romantic composer Franz Liszt, called Au lac de Wallenstadt. The piece is part of a collection of solo piano works inspired by the composer's travels to Switzerland in the 1830s.
