The country of Brenzone covers an area of 50 square meters. The area includes the towns of Castello, Castelletto, Marniga, Magugnago, Porto and Assenza plus other smaller villages that are closer to the mountainside.
The town has not grown much in size and has preserved many characteristics of the past...many quaint fishermen’s villages clustered around a port and many rustic rural hamlets in the hills.
The small island of Trimelone, which up until a few years ago was used as a military depot, sits near the shore in front of Assenza.
As tourism is its main industry, the lakeside is lined by many hotels, residences and camping sites. Numerous restaurants offer local dishes and specialties from the area (fish, olive oil, wine, etc.).
Many are the different kind of sports: sailing, windsurf, waterski, diving, paragliding, mountain bike, trekking.
