Lake Onega in Karelia: Kizhi, Petrozavodsk, and Nature
Lake Onega is the second-largest lake in Europe. It lies within the territory of three regions of the Russian Federation: Leningrad Oblast, Vologda Oblast, and the Republic of Karelia. Along with Lake Ladoga, Lake Onega is considered one of Karelia’s main attractions.
Karelia has around 60,000 lakes, which is why it is known as “the Republic of Lakes.” Lake Onega is “the Tsar of Lakes.” Its surface area exceeds 9,000 square kilometers—about the same as that of four countries the size of Luxembourg. The lake’s maximum depth is over 120 meters. It has many large and small islands. The largest is Bolshoy Klimetsky Island. The best-known is Kizhi Island, home to a unique open-air museum of architecture.
Petrozavodsk is the capital of Karelia. It lies on the shore of Lake Onega and serves as a distinctive landmark separating the lake into northern and southern parts. The part of the lake north of Petrozavodsk belongs to Karelia. Here are the bays of Little Onego and Big Onego. The northern part of Lake Onega is the deepest. The somewhat shallower southern part includes Central Onego (Middle Onego), Southern Onego, and Svir Onego. It is here, in the southern part of the lake, that the Svir River begins, connecting Lakes Onega and Ladoga.
Cruises on Lake Onega are very popular. They usually depart from Saint Petersburg and continue via Lakes Onega and Ladoga, calling at Kizhi and Valaam. The best time to plan a cruise is early summer, during the “white nights.”
Lake Onega is rich in fish. Its waters promise a good catch: salmon, zander, pike, and eel. The lake is home to more than 40 fish species in total. It is no wonder that fishing is a popular pastime in Karelia.

Planning a trip to Lake Onega
The lakeshores, islands, and Karelia provide a useful starting point for a trip to Lake Onega. The main points of interest are the lakeshores, islands, and connections with Petrozavodsk or other destinations in Karelia.
Lake Onega as a Northern Russia travel destination
Lake Onega shapes Karelia through its size, islands, lakeside settlements, and connection to Petrozavodsk. The island of Kizhi, known for its wooden architecture, is especially famous, but the quiet shores, waterways, and northern landscapes are also part of what defines the destination. When planning, it is important to decide whether the focus is on culture, nature, or onward travel. Check current information on boat connections, weather, and seasonal access before arranging a specific trip.
Between Karelia and northwestern Russia
Lake Onega lies mostly within the Republic of Karelia; its southern shores extend into Leningrad and Vologda Oblasts. It is connected to Lake Ladoga by the Svir River, while waterways lead north toward the White Sea. This location explains why the lake is part of both the Karelian landscape and the wider waterway network of northwestern Russia. Petrozavodsk lies on the western shore and is the main urban base for getting oriented around the lake.
Kizhi and the islands
The best-known island is Kizhi, home to its open-air museum and the UNESCO-listed Pogost. Its wooden architecture is the focus of many visits, but the island is only one part of an extensive landscape of islands and bays. Distances across the water are considerable. If you plan to visit Kizhi or other islands, check the departure point, travel time, return trip, and weather conditions in advance using current information from operators and authorities.
Petrozavodsk as a base
Petrozavodsk is a good base for combining the waterfront promenade, the city’s history, and potential excursions. When deciding on a trip, reliable connections and sufficient time buffers matter more than trying to fit in as many stops as possible. Boat schedules, entry requirements, and the current security situation can change, so check them directly with official sources before making concrete travel plans.
Connecting Kizhi, Petrozavodsk, and the lakeshore
A trip to Lake Onega begins with choosing between Petrozavodsk, the museum island of Kizhi, and other lakeside or nature destinations. Kizhi is not an ordinary city sightseeing stop, but an island destination requiring its own transport connection and a schedule that depends on the weather. Allow generous buffers for water travel, waiting times, and the return journey.
For Karelia, compare Karelia, Petrozavodsk, Kizhi, Lake Ladoga, Valaam, and Kivach as different stops. Solovki, Nature and landscapes, and Culture and history round out the options.
