Experience the authentic villages, magnificent cities and ever-changing landscapes of the River Danube as it meanders across Southern Germany from its source to the romantic city of Passau. Touring along the Danube cycle path and quiet country roads, the cycling is undemanding but if 12-days in the saddle sounds like a lot, opt for an electric bike. Follow the river as it flows past green plateaus and snakes between chalky cliffs. On day two it disappears into the rock and bursts back out through limestone river-cliffs a few days later. The crooked houses and contemporary architecture of Ulm are a highlight halfway through and the World Heritage landmarks in Regensburg are magnificent. Vibrant towns and half-timbered villages are perfect for pit-stops and, as you pedal alongside the riverbanks, look up to see baroque monasteries, Roman ruins and fairytale castles.
