How Deep is Lake Garda. Exploring the Depths of Italy’s Largest Lake
Beneath the crystal clear waters of Lake Garda lies an underwater landscape still being uncovered. As the largest lake in Italy, Garda stretches 32 miles in length but reaches depths over 1,000 feet in places. Its gleaming surface and quaint villages evoke Mediterranean charm, yet hidden below is a world shaped over millions of years.
Carved by a long-vanished glacier, Lake Garda’s depths reflect its Ice Age origins. A deep valley running north-south divides the lake into two major basins. The southern section plunges rapidly to over 300 meters offshore, with its deepest recorded sounding of 346 meters near Tignale. The flatter northern basin averages 50-100 meters in depth, reaching a maximum of 263 meters.
This bathymetry results from Garda’s position within a major fault zone bordered by limestone cliffs and moraine hills. Softer sediments fill the central rift valley, while robust tributaries feed the lake year-round. The outlet Mincio River prevents overflow. In concert, these geological forces sculpted Lake Garda’s irregular underwater topography over eons.
Ongoing research is illuminating Garda’s elusive deep ecosystems. Through bathymetric mapping and scientific diving, features like underwater canyons, thermal streams, and ancient ruins have been revealed. More mysteries likely await in the dark lake garda depths.
While Garda’s beauty captivates from above, the lake’s true scale only becomes clear below the surface. Its extreme depths and hidden contours are integral to its character. Lake Garda remains an environment forged as much by the forces within its depths as the spectacular landscape of the surrounding Italian Alps. Even locals unaware of what lies beneath the lake they love would surely marvel at the secrets Garda holds in its unseen depths.

Sizing Up Italy’s Spectacular Lake Garda.
With its postcard-perfect villages, soaring cliffs, and azure waters set against a dramatic Alpine backdrop, Lake Garda offers some of Italy’s most spectacular scenery. But beyond its stunning natural beauty, this renowned lake has another claim to fame – its mammoth size.
How Long is Lake Garda
Stretching across Northern Italy’s Lombardy and Veneto regions, Lake Garda is the country’s largest lake. It measures an impressive 51.6 km (32 miles) long, while spanning 19.6 km (12 miles) at its widest point. The total surface area covers 370 km2 (143 square miles).
To put that in perspective, Lake Garda’s surface is larger than well-known lakes like Como, Maggiore, and Lugano combined. It has double the area of famous Lac Leman in Switzerland. Only five other lakes in Italy exceed Garda’s immense proportions.
Let’s explore the sheer scale of Lake Garda through facts and figures:
Length: 51.6 km (32 miles)
Spanning over 50 kilometers in length, Lake Garda is impressively long. If stood upright, it would be taller than 50 Eiffel Towers stacked end-to-end. It’s nearly the same length as the English Channel between England and France.
At 52 km, you could walk the entire length of Lake Garda’s shoreline in about 18 hours at a leisurely pace. Or you could drive it in just under an hour when traffic is light. Ferries and hydrofoils connecting towns like Sirmione and Riva del Garda take advantage of Garda’s elongated shape.
Width: 19.6 km (12 miles)
While long, Lake Garda is also exceptionally broad. Its widest point measures 19.6 kilometers across from San Vigilio to Brenzone on the eastern shore.
To cross the lake’s width at this point would take a moderate swimmer around 5 hours, or a motorboat zipping at 30 mph approximately 24 minutes. The imposing Italian Alps and softer moraine hills framing the water accentuate Garda’s wide horizons.
Surface Area: 370 km2 (143 square miles)
When combined, Lake Garda’s immense length and width give it a surface area of 370 square kilometers. That’s equivalent to 143 square miles.
To visualize how sizable that is, you could fit the city of Chicago (606 square km) inside Lake Garda’s surface area with room to spare. It’s over 20 times larger than other vacation lakes like Lake Tahoe in California and Nevada.
Shoreline Length: 158 km (98 miles)
The shoreline encircling Lake Garda’s huge surface area stretches approximately 158 kilometers, or 98 miles.
Driving at 55 mph, you’d need nearly 2 hours to complete a loop around the entirety of Lake Garda’s perimeter. Fortunately, you can stop in charming villages like Sirmione and Malcesine along the way.
The mountainous terrain surrounding the lake creates a convoluted shoreline with long peninsulas and indented bays that add to its length. This varied geography contributes to Garda’s stunning scenery.
Volume: 49 km3 (12 cubic miles)
Containing 49 billion cubic meters (59 billion cubic yards) of water, Lake Garda ranks among the largest lakes in Europe by volume. That’s equal to around 12 cubic miles of water.
To help conceptualize just how much water that is, Lake Garda could flood the entire island of Manhattan up to a height of over 300 feet. It’s enough liquid to fill 19 million Olympic swimming pools.
Max Depth: 346 meters (1,135 feet)
In some parts, Lake Garda plunges to impressive depths. Its deepest point of 346 meters (1,135 feet) was recorded just off the town of Tignale along the southwest banks.
To reach this depth, you’d need to stack up nearly 7 Statues of Liberty on the lakebed. It rivals famous deep lakes like Lake Tahoe, which measures 501 meters at its deepest point. Underwater cliffs and valleys carved by glaciers account for Garda’s Mediterranean blue hue.
Lake Garda rightfully deserves its distinction as Italy’s largest lake based on its sprawling dimensions. While mere statistics can’t convey the full beauty of Garda’s turquoise waters set against craggy peaks, they help quantify the sheer mammoth scale of this natural wonder. Whether measured in miles, acres, or cubic meters – Lake Garda represents one of Europe’s grand lake landscapes.
lake garda deepest point
At its deepest point, the lake reaches a maximum depth of 346 meters (1,135 feet). This deepest section is situated between the towns of Castelletto di Brenzone and Muslone along the lake’s eastern shore. With depths exceeding 300 meters, Lake Garda is one of the deepest lakes in Europe. The incredible depth is a result of the lake filling a glacier-carved valley surrounded by mountains. The lake’s deepest point provides a unique environment and habitat for aquatic life and contributes to the lake’s scenic natural beauty.
