Alster Lake
Hamburg
Outer Alster Lake, or Außenalster, is the larger of two artificial lakes formed by the Alster River within Hamburg city limits. Covering 1.64 square kilometers, it is shallow with an average depth of 2.5 meters and fed by several rivers and canals. Historically, the term "outer" refers to its location outside Hamburg's 1625 city walls, which were removed in 1804 but preserved the division between the two lakes. Today, the lake is a hub for recreational activities like sailing and rowing, with several historic rowing clubs based around it. The surrounding districts include affluent residential areas with villas, consular missions, and luxury hotels. Public parks and green banks encircle the lake, offering a popular 7.6-kilometer path for joggers and walkers. The lake hosts cultural events such as the annual Cherry Blossom Festival organized by Hamburg's Japanese community and, occasionally, winter festivals on the frozen lake. Despite its clean water, swimming is discouraged due to boat traffic and water conditions. The lake's western shore developed earlier as a wealthy suburb, while the eastern shore evolved later with more urban density. Bridges like Lombardsbrücke and Kennedybrücke span the lake, connecting key city districts. Außenalster remains a cherished natural and cultural landmark in Hamburg, blending urban life with outdoor leisure.

Astuce: The best time to visit Outer Alster Lake is during late spring for the Cherry Blossom Festival or in winter if the lake freezes sufficiently for the Alstereisvergnügen festival. Visitors are advised to enjoy sailing and jogging along the 7.6 km public pathway. Swimming is not recommended due to watercraft density. Booking accommodations near the lake in advance is suggested, especially during festival periods. Many streets around the lake are prestigious residential areas with limited public parking, so using public transport or cycling is advisable.

Histoire
The Outer Alster Lake was historically the part of the Alster River lake system lying outside Hamburg's city walls, built in 1625.
The walls and ramparts were dismantled in 1804 and converted to parks, but the lake's division remained.
During World War II, camouflage was applied to the adjacent Binnenalster to confuse enemy bombers, and a fake Lombardsbrücke was created on the Außenalster along with an anti-aircraft unit.
The western shore developed as a wealthy suburb in the late 18th century, while the eastern shore developed later in the 19th century under city financial authority.
Today, the lake is a prominent recreational and cultural site within Hamburg.
