Lake Maggiore is 68 kilometres (42 miles) long, and 3 to 5 km (2 to 3 miles) wide, except at the bay opening westward between Pallanza and Stresa, where it is 10 km (6 mi) wide. It is the longest Italian lake, but Lake Garda has a greater area. Its mean height above the sea level is 193 metres; a deep lake, its bottom is almost everywhere below sea-level: at its deepest, 179 metres below. Its form is very sinuous, so that there are few points from which any considerable part of its surface can be seen at a single glance. If this lessens the effect of the apparent size, it increases the variety of its scenery. While the upper end is completely alpine in character, the middle region lies between hills of gentler form, and the lower end advances to the verge of the plain of Lombardy.
