Castelli di Cannero: Boat Transfer & Audio Guide to Lake Maggiore's Ruined Island Fortress

About This Tour

Lake Maggiore is famous for the Borromean Islands — Isola Bella with its terraced Baroque gardens, Isola Madre with its botanical collections, Isola dei Pescatori with its fishing village streets. All three are reachable from Stresa and draw the majority of the lake's visitors. But there is a second pair of Borromeo-owned islands on the lake that almost nobody visits: the Castelli di Cannero, 25 kilometres north along the western shore, two rocky outcrops rising straight from the water near Cannero Riviera, each carrying the ruin of a medieval castle above the lake surface. They are harder to reach than the Borromean Islands — no regular ferry stops here, no car park visible from shore, no tourist infrastructure on the northern lake road that would tell a passing visitor to stop. The only way to reach them is by a small boat from Cannero Riviera, Cannobio, or Luino, coordinated with the official lake navigation schedule. This is what the boat transfer and audio guide product covers: the approach by water, landing on the island, exploring the ruins with audio context, and the return crossing. The history of the Castelli di Cannero involves one of Lake Maggiore's less celebrated chapters. In the late 14th and early 15th centuries, the two islands were controlled by the Mazzarditi family (also known as the Vitaliani), a local clan who used the lake castles as a base for piracy and extortion — attacking merchant boats on the lake, demanding passage fees, and raiding the settlements along the western shore. Lake Maggiore's position as a commercial corridor connecting the Po plain to the Alpine passes through Locarno and Bellinzona made controlling a stretch of the navigable lake highly profitable. The Mazzarditi held the islands for several decades before the Borromeo family, the dominant aristocratic power on Lake Maggiore from the mid-15th century onward, took them by force and demolished the fortifications. The ruins standing on the two islands today are the aftermath of that 15th-century demolition rather than the original lake fortresses. The Borromeo family acquired most of the significant real estate on Lake Maggiore between the 14th and 17th centuries. Their portfolio grew to include the Borromean Islands (Isola Bella, Isola Madre, and Isola dei Pescatori), the Rocca di Angera on the eastern shore, and significant mainland holdings around Stresa and Arona. The family remain the owners of most of this property today, and the Castelli di Cannero are managed by Terre Borromeo, the Borromeo estate company that also operates the Rocca di Angera, Isola Bella, and the other family attractions on the lake. The boat transfer and audio guide product is operated by the same entity, making this effectively a visit to a lesser-known corner of what is still a privately held medieval and Renaissance estate on a working Italian lake. The ruins themselves, while fragmentary, are compelling in their setting. The two islands are small — barely large enough for the castle footprints — and the masonry rises directly from the water without any foreshore or bank between the lake and the walls. From the boat, and from within the ruins themselves, the view across the lake takes in the western shore mountains and the Swiss border peaks to the north. The water approach cannot be replicated by any road-based visit, and the photographic opportunities from a small boat at water level — castle walls reflected in still water, the Alps behind, no other tourists visible — are different in kind from the crowded midday terrace at Isola Bella. Visiting the Castelli di Cannero makes most sense when combined with the rest of what the western shore of Lake Maggiore offers. Cannero Riviera itself is a small resort town with a historic centre worth 30 minutes; Cannobio, 5 kilometres north, is one of the most attractive lake towns on the Italian side, with a medieval arcaded waterfront. If you are also visiting the Borromean Islands or [Rocca di Angera](/castles/italy/rocca-di-angera) on the eastern shore — the most complete medieval fortress on Lake Maggiore, also a Borromeo property — the Castelli di Cannero adds a genuine historical and visual contrast: ruined and inaccessible versus intact and staffed, island-standing versus hilltop, north lake versus central lake. The two represent the geographic and architectural range of what the Borromeo family built and holds on Maggiore. **Cancellation policy note:** this product is non-refundable once booked — there is no free-cancellation period, which differs from most boat tours and day trips on this site. Check the GYG listing for current weather-related conditions and confirm before booking if your schedule has flexibility constraints.

Highlights

• ✓Audio guide included — covers the history of the Mazzarditi pirate clan who held the islands and the Borromeo family conquest that left them in ruins
• ✓Managed by Terre Borromeo — the same Borromeo family estate company that operates Isola Bella, Rocca di Angera, and the other great Borromeo properties on the lake
• ✓Lake Maggiore's least-crowded major historic site — the Borromean Islands at Stresa receive hundreds of thousands of visitors; the Castelli di Cannero sees a fraction
