As Central Europe's third largest lake, cycling around the lake is special in that you visit all three countries in a week. Hosting a huge 270km lakeside cycling path, it's a beautifully flat journey from one country to the next, where you'll take in the sights and scents of cherry orchards, wildflower fields and daisy-strewn meadows.Cross the mighty Rhine Delta that straddles the border between Austria and Switzerland and encounter wonderful wildlife, including kingfishers hidden in the reeds. Take a refreshing dip in the turquoise waters during stop-offs, visit half-timbered frescoed towns for lunch (kretzer (perch) and zander (pike-perch) are Konstanz specialities), and then admire the myriad of Baroque churches and Gothic cathedrals.Brimming with historical and cultural highlights, jump off your bike to visit fairytale Meersburg boasting twin castles, steep streets and vine-covered hillsides. Get a true taste of Germany when cycling through the Bavarian vineyards - local Muller-Thurgau wines come from Riesling and Silvaner grapes for which Lake Constance is famous. For chocolate-lovers, mediaeval Stein am Rhein boasts an array of lovely chocolate shops, and you can visit the 11th century monastery while you're there.
