Beautiful views of the lake with lots of things to see and do! Bike paths are generally very well-maintained, and separated from street traffic (usually), so you can enjoy the scenery without too much stress.

On my second "Around Germany" cycling trip (this time going left-handed), I cycled along the Swiss side of Lake Constance. Even though the bike paths were consistently beautiful, most of the route was boring – the German side of the Lake Constance Cycle Route is much more varied and beautiful.

The baroque old town boasts sights such as the town hall, built between 1747 and 1750, with its rich Rococo decorations, and the 14th-century Church of St. Pelagius. The Thur Bridge, built in 1487, is one of the most important late medieval bridges in Switzerland. In the 9th century, Bischofszell was given the name Episcopalicella by its founder, Bishop Salomo. This translates as "the bishop's cell." Bischofszell Castle was the bishop's castle and dates back to the 13th century.
