These conditions make them ideal for kayaking, fishing, and leisurely boating. During winter, river temperatures typically range from 1–5°C (34–41°F), with smaller or slower-moving rivers occasionally seeing thin layers of ice.
Schleswig-Holstein is also home to a number of lakes, such as Großer Plöner See and Selenter See, which are popular recreational spots.
