Aficionados hail Holstein Switzerland as canoeing country, and with stamina or time, you can paddle through an interconnected mosaic of lakes all the way to Kiel – the 50km trip has been done in a long day, but most people allow three or four. A booklet of the route, Paddeln, is available either from the tourist office or as a download from its website. Boote Keusen Sielbecker, Sielbecker Landstr. 17 (04521 42 01, boote-keusen.de), in northerly suburb Eutin-Fissau, has Canadian canoes and can provide boat transport back from wherever you end up. A great trip.
