Swimming in the Elbe may sound tempting, but it is generally not recommended due to strong tides and busy shipping traffic. Water quality can also fluctuate, which can pose health risks. Numerous ferries and river cruises offer the opportunity to be on the water without the risks associated with swimming. Still, there are beaches within Hamburg, such as Elbstrand, where you can indulge your water cravings in a safer way. Make sure you only swim in officially approved swimming areas and follow the safety guidelines.
