Ordered leg totals agree within rounding. Stop distances are approximate sums of rounded legs. Stops, delays, approach and any separate return travel add time. Basis: producer-declared routed record.
Reading history stays on this device. My road watch requires a separate selection; opening it does not subscribe this ride.
Distance and riding time are measured on the routed road. Check local closures and conditions before you ride.
A 225 km round trip from Arbon - roughly 4 h 43 in the saddle. On the way it passes Konstanz-Hinterhausen, Hornstaad-Hörnle, Sipplingen-Osthafen and Unteruhldingen-Stollenwiesen. It crosses from Switzerland into Germany - carry ID and check vignette or toll rules.

Waypoint introductions and full write-ups
1. Bleiche 2-3
Arbon sits on the Swiss shore of Lake Constance, in the canton of Thurgau, and just outside the town, on land that was once lake shore, lies one of the most remarkable prehistoric sites in Europe. At Arbon-Bleiche, archaeologists excavated a Neolithic village of wooden houses built on the edge of the lake around 3400 BC. Because the wood was preserved in waterlogged ground, tree rings allowed the village to be dated almost to the year: it was built, lived in for about fifteen years and then destroyed by fire. The finds, from pottery and tools to textiles and food remains, gave a detailed picture of how these early farmers lived, and Arbon counts among the Swiss sites in the Alpine pile-dwelling inscription of 2011. There is nothing to see at the site itself, which is now under buildings and fields; the finds are displayed in the Thurgau archaeological museum in Frauenfeld.
May refer to an earlier itinerary; verify against your selected route before riding.
Planning note
Bleiche 2-3 is where the day begins. Next is Konstanz-Hinterhausen.
2. Konstanz-Hinterhausen
There is nothing to see at Konstanz-Hinterhausen, and that is precisely the point. Below the surface of Lake Constance, along the shore near the city, lie the remains of prehistoric pile dwellings: wooden posts, floors, pottery and food remains preserved in the mud for thousands of years. They are part of the Prehistoric Pile Dwellings around the Alps, a World Heritage site that spans six countries and over a hundred locations. Archaeologists dive to study them, but the rest of us have to make do with the view of the lake and a bit of imagination.
May refer to an earlier itinerary; verify against your selected route before riding.
Planning note
Konstanz-Hinterhausen comes up about 34 km into the recorded legs. Next is Hornstaad-Hörnle.
3. Hornstaad-Hörnle
On the Höri peninsula, the long finger of land that pokes into the Untersee arm of Lake Constance, the shallow water off the point of Hornstaad hides the remains of a village burned some six thousand years ago. Hornstaad-Hörnle is one of the most important Neolithic sites in the region: the settlement was destroyed by fire, and the charred remains, sealed in lake mud, preserved an extraordinary record of daily life, including food, textiles, tools and house timbers, which dendrochronology has dated with great precision. It is part of the World Heritage inscription of the prehistoric pile dwellings around the Alps, and finds from the site are displayed in museums around the lake.
May refer to an earlier itinerary; verify against your selected route before riding.
Planning note
about 68 km into the recorded legs you reach Hornstaad-Hörnle. Next is Sipplingen-Osthafen.
4. Sipplingen-Osthafen
At Sipplingen the north shore of Lake Constance changes character. The Überlinger See, the long north-western arm of the lake, is hemmed in here by steep molasse cliffs and wooded slopes rising to the Sipplinger Berg, and the village sits on a narrow strip between the hill and the water. Below the surface off the eastern harbour lie the remains of prehistoric pile dwellings, villages of wooden houses built on stilts along the shore some five to six thousand years ago. They are part of the World Heritage site of prehistoric pile dwellings around the Alps.
May refer to an earlier itinerary; verify against your selected route before riding.
Planning note
Sipplingen-Osthafen, about halfway. Next is Unteruhldingen-Stollenwiesen.
5. Unteruhldingen-Stollenwiesen
Unteruhldingen is where most people first meet the prehistoric lake dwellers of the Alps, thanks to the Pfahlbaumuseum, an open-air museum of reconstructed houses on stilts standing in the shallow water of Lake Constance. It started in the 1920s and has been adding houses ever since, and walking along the wooden walkways between thatched huts gives you a vivid idea of village life thousands of years ago. The real archaeological sites, like Stollenwiesen just offshore, lie underwater, a series of settlements preserved in lake mud and listed by UNESCO in 2011 as part of the Prehistoric Pile Dwellings around the Alps.
