At its northern end the shores are nearly level, while on the west shore the wooded promontory of Buonas (with its castles, old and new) projects picturesquely into the waters. The principal place on the lake is the town of Zug. Three railways follow the shore of the lake, one from Zürich via Zug and Arth-Goldau to the St Gotthard, one from Lucerne via Arth-Goldau to the St Gotthard and one from Zürich via Zug to Lucerne.
