The lake's jagged banks are surrounded by the Pennine and Lepontine Alps, and Lugano Prealps. Prominent peaks around the lake are the Gridone, Monte Tamaro, Monte Nudo and the Mottarone. The highest mountain overlooking Lake Maggiore is Monte Rosa (), located about west of it. The western bank is in Piedmont (provinces of Novara and Province of Verbano-Cusio-Ossola) and the eastern in Lombardy (province of Varese), whereas the most northerly section extends into the canton of Ticino, where it constitutes its lowest point above sea level as well as that of Switzerland. The culminating point of the lake's drainage basin is the Grenzgipfel summit of Monte Rosa at above sea level.
