Lake Iseo, Lake Garda or Lake Como: the three lakes compared for buyers

The three lakes in figures

All three lakes lie wholly or partly in Lombardy. The figures come from Wikipedia:

• Lake Garda: 370 square kilometres, up to 346 metres deep, 51.6 kilometres long, the largest lake in Italy. It spans Lombardy, Veneto and Trentino-Alto Adige, bordering the provinces of Brescia, Verona and Trento.
• Lake Como: 146 square kilometres, up to 425 metres deep, 46 kilometres long, the third-largest lake in Italy after Garda and Maggiore. It is Y-shaped and lies in the provinces of Como and Lecco.
• Lake Iseo: 65.3 square kilometres, up to 251 metres deep, the fourth largest lake in Lombardy, split almost equally between the provinces of Brescia and Bergamo.

Lake Garda

Lake Garda has 26 municipalities. Among the largest towns are Desenzano del Garda (about 29,200 inhabitants), Arco and Riva del Garda (about 17,500 to 17,900 each). Sirmione, Salò, Malcesine and Garda are also well known.

Lake Como

The main towns are Como and Lecco at the two lower ends, plus Bellagio, Varenna and Menaggio. The Y shape was created by the Adda glacier of the Ice Age.

Lake Iseo

Lake Iseo lies between Brescia and Bergamo, about 20 kilometres north-west of Brescia. Iseo and Sarnico are among the largest towns, and Monte Isola sits in the middle of the lake. Franciacorta begins to the south.

What property costs

Prices differ greatly by town and location. A Casa.it analysis from May 2026 gives average apartment prices of 4,768 euros per square metre at Lake Garda (up 9 per cent year on year), 4,393 euros at Lake Lugano and 3,765 euros at Lake Como (up 6 per cent). For Lake Iseo it only gives the 6 per cent rise, no price.

For Iseo itself, the portal RealAdvisor gave about 3,100 euros per square metre for apartments and about 2,730 euros for houses in July 2026. Individual towns are well above that: Sirmione on Lake Garda at about 5,100 euros for apartments (RealAdvisor, July 2026), Menaggio on Lake Como at about 5,460 euros (Casa.it, May 2026). On the upper part of Lake Como, Colico, Bellano and Perledo are below 3,100 euros.

The figures come from different sources and methods (asking prices, estimates) and are not directly comparable. They show the order of magnitude: according to the data we found, Lake Iseo is below the averages of Lake Garda and Lake Como.

How to decide for yourself

Instead of asking which lake is the most beautiful, these questions help:

• Main residence or holiday home? It changes the taxes when you buy and everyday life, including winter and dealing with authorities.
• How far must it be to the airport, railway station, work and doctor? That can only be settled on site and on the map.
• Which budget per square metre fits, and which towns are below it? Within one lake the differences are larger than between lakes.
• How much bustle do you want in the season? Visit the town outside the holiday season before you decide.
