Frequently Asked Questions
What's the most popular dive site in Lake Como, Italy?

Another well-known spot is the underwater statue 'Christ of the Abyss' in Magreglio. For a less-crowded experience, explore the cliffs near Onno or find smaller wrecks known to local guides. These sites offer similar geology with fewer divers, providing a more serene exploration of the lake's dark, beautiful depths.
What water temperature is it like throughout the year diving in Lake Como, Italy?
The water temperature in Lake Como, Italy, is characterized by a strong thermocline. In summer (June-August), the surface can warm up to 20-24°C (68-75°F). However, below 10-15 meters, the temperature plummets to a consistent 5-8°C (41-46°F) year-round. In winter, the surface temperature also drops, making conditions extremely cold. Divers must be prepared for cold water on every dive, regardless of the season.
When is the best time to visit Lake Como, Italy?
The best time for diving in Lake Como, Italy, is from May to October. During these months, the surface water is warmer, air temperatures are pleasant, and weather conditions are more stable. Summer (July-August) offers the warmest weather but is also peak tourist season. Spring and autumn often provide the best underwater visibility and have fewer crowds, making it ideal for divers looking for clearer conditions. Winter diving is possible but reserved for highly experienced drysuit divers.
What's the visibility like during the dive season in Lake Como, Italy?
Underwater visibility in Lake Como, Italy, is highly variable. It is generally not a crystal-clear environment. On average, you can expect visibility ranging from 5 to 15 meters (16-50 feet). Conditions are often best in the spring and autumn when there is less boat traffic and fewer plankton blooms. After heavy rain or during the summer melt, visibility can be significantly reduced, sometimes dropping to just a few meters, especially near the surface.
Are there any seasonal migrations or special events (e.g., manta rays, whale sharks) in Lake Como, Italy?
As a freshwater alpine lake, Lake Como, Italy, does not have seasonal migrations of large marine animals like manta rays or whale sharks. The 'special events' for divers here are related to conditions rather than wildlife. The main attractions are the dramatic underwater cliffs, historical wrecks, and unique geological formations. The fauna is typical of European freshwater lakes, so divers should set their expectations accordingly and focus on the unique topography.
What marine life can I expect to see in Lake Como, Italy?
The aquatic life in Lake Como, Italy, is typical of a deep, cold freshwater lake. Divers can expect to encounter species such as European perch, northern pike, chub, and eels. In the deeper, darker sections of the lake, it's possible to spot the elusive burbot. The ecosystem is not as colorful or dense as a tropical reef; the primary draw for diving here is the incredible geology, submerged artifacts, and wrecks rather than abundant wildlife.
What thickness wetsuit should I wear in Lake Como, Italy?
A drysuit is highly recommended for diving in Lake Como, Italy, regardless of the season. The water temperature drops to 5-8°C (41-46°F) below the thermocline, even in summer. A 7mm semi-dry wetsuit with a hood and gloves is the absolute minimum but will likely be uncomfortable for most divers on deeper or longer dives. For safety and comfort, and to fully enjoy the deep, cold sites, a drysuit is the appropriate thermal protection.
How do I get to Lake Como, Italy?
To get to Lake Como, Italy, fly into one of Milan's major airports: Malpensa (MXP), Linate (LIN), or Bergamo (BGY). From Milan, the most convenient way to reach the lakeside towns is by train (to Como, Lecco, or Varenna) or by renting a car. The drive offers scenic views but roads around the lake can be narrow and busy, especially during peak season. Most dive centers are located in towns accessible by road or local ferry.
Should I book a liveaboard or stay on shore in Lake Como, Italy?
