The Alzette River, flowing through Luxembourg and parts of France, is a smaller river known more for its scenic charm and historical landmarks than for swimming. Due to its relatively mild current and narrow course, its water temperature generally varies with the season, reaching around 15°C to 20°C (59°F to 68°F) in the warmer months. In winter, the temperature can drop significantly, often falling below 5°C (41°F). This fluctuation, along with the river's modest depth and occasional pollution issues, makes it less popular for swimming compared to larger rivers in the region.

There are no official swimming areas along the Alzette, partly due to water quality concerns in urban areas like Luxembourg City. However, people often enjoy walking, cycling, and picnicking along its banks, particularly in scenic areas where the river passes through lush landscapes and historic sites. Although swimming is not recommended, the Alzette offers a pleasant environment for recreational activities close to nature.
