From the source of the River Rhine to Lake Constance.

The River Rhine has its source at an altitude of 2345 metres, in a small shimmering lake surrounded by high peaks. From Lake Toma, the small torrent cascades down the hills, joins other streams and becomes increasingly larger as it continues its journey over 1233 kilometres through Switzerland, Germany, France, to its mouth in the Netherlands.

From Andermatt to Lake Constance, EuroVelo 15 covers a large loop along the powerful Alpine river. Along the whole of this route located in mountain settings, cyclists can appreciate several different landscapes. First of all, it passes through the Surselva, the largest Romansh region of the Grisons (Graubunden) and its impressive [...]


, a breathtaking ravine created by the falling rocks of the mountain more than 10 000 years ago. From Chur, the oldest town in Switzerland with numerous medieval streets, the valley broadens slightly and crosses the Grisons district – the Bündner Herrschaft, a small tourist and wine-growing region which spreads over the right bank of the Rhine to the border with the Principality of Liechtenstein. The EV15 finally reaches the largest freshwater delta in Europe, which opens onto Lake Constance, known as “the heart and soul of Europe”. The landscape surrounding the shimmering green and silver lake is a source of some old natural heritage. Despite some very busy banks, the lake maintains its idyllic characteristics, with its castles and orchards. Constance is located on the West side of the lake. As a university town, it offers a multitude of leisure activities and has managed to maintain its traditional position as a centre of excellence for trade and culture. This part of the EV15 is undoubtedly the most demanding part for the cyclists, as it begins by a climb up the Oberalp pass, perched at an altitude of 2046 metres, before sweeping down to Disentis and continuing its journey towards the North-East.

  • Chur

    Administrative, religious and historical capital of the Grisons district, Chur is considered as Switzerland's oldest town. Built from the 5th century under the name of “Curia Rhaetorum”, this medieval town, of which a large part of the town-centre has been pedestrianised, is an essential stopping-place for visitors travelling along the Rhine. The narrow streets, flowery fountains, lively little squares and the multitude of restaurants and shops encourage visitors to take a stroll. The town is also the departure point for the Rhaetian railway and its lines certified as World Heritage by UNESCO and its famous lines of the Bernina and Glacier Express.

  • Abbey of St Gall

    Located a few kilometres to the south of the Rhine is the former Saint Gallen Monastery. After the city was founded in 612, the first Benedictine Monastery was founded on the site in about 719. Switzerland's second oldest monastery and one of the biggest Benedictine monasteries in Europe, it was highly influential cuturally for over 1200 years. Distinguishing features are the late Baroque collegiate church and the 160.000-book Baroque library with rococo furnishings. 2.200 codices of which 500 are over 1000 years old. The library therefore houses one of the richtest collections of medieval books belonging to the German-speaking part of Europe.

  • Lake Toma

    Located at the foot of Piz Baduz at an altitude of 2345 metres, Lake Toma is considered to be the source of the River Rhine. A one-hour walk away from the Oberalp Pass in Graubünden, it is the only place where the river can be crossed in one stride. With a surface area of 2.5 hectares, it is also the start of a 1230 kilometre journey through four European countries to the North Sea.

  • Versamer Tobel Bridge

    The wild and eroded landscape of the Versam region, upstream from Bonaduz, is not at all easy to pass through. However, a mountain road, one of the most spectacular routes in the Swiss Alps, was built in the 1880s, with several tunnels, sharp bends, and retaining walls. The bridge spanning over the Versamer Tobel, a daring steel structure built in 1897, peaks at 70 metres above the Rabiusa, a tributary of the Rhine.
