evidence: Measuring 64 km in length and 12 km at it widest point, Lake Constance, which is sited at the tripoint of Switzerland/Germany/Austria, is the third largest lake in Central Europe. Scheduled boat services, allied with a range of attractive year-round offers and run by various companies from all three neighbouring states, operate on Lake Constance. [...] Boats, buses, cableways and railways can all be used conveniently and easily with the Lake Constance EuRegio cross-national day card, as well as the multiple-day Lake Constance Experience Card which also offers free admission to 195 excursion destinations. Popular cruise destinations to nearby non-Swiss terrain include Mainau Island with its flower gardens and parks, and Reichenau peninsula with its UNESCO-World-Heritage-listed monastery. [...] The gently undulating landscape around Lake Constance is a paradise for active holidaymakers. This excursion and relaxation region offers countless water sports opportunities, hiking and walking trails, but especially skating routes and cycling tracks. A favourite classic is the Lake Constance Cycle Path, which leads right around the lake.
