Berlin, with its many lakes, and sailing (Segelsport) are a match made in heaven. Because the city is so flat and sheltered from strong winds, it is a good place for a beginner to start. Boats are available for rent on many lakes, as are canoes and kayaks for those who wish to move at a slower pace. The Berliner Seglerverband is the umbrella organisation for the 114 sailing groups in the city, and organises classes for youths and adults, as well as regattas (www.berlinerseglerverband.de). For more adventurous activities such as rafting and waterskiing, see Watersports.
