Also known as the Bodensee, Lake Constance straddles Germany, Austria, and Switzerland and is the third-largest lake in Central Europe. It's an excellent destination at any time of the year; summer brings the opportunity to go for a boat trip, lounge on one of the many beaches, or cycle along the shore, while winter visitors can relax in one of the thermal baths, visit a Weinfest, or spend the afternoon in one of the many castles. Due to the lake's unique location, visitors can start the day in Austria, pass through Switzerland in the afternoon, and make it to Germany in time for dinner.
