Wallsee is the kind of Danube town you only notice if you slow down: a market square, a big castle on a rock above the river, and a long, quiet waterfront where the cycle path runs past willows and moored boats. Beneath the streets lie the remains of a small Roman fort, one of the posts that lined the river frontier of the province of Noricum, and archaeologists have also traced a larger fort nearby. Both are part of the Danube Limes World Heritage listing inscribed in 2021, though above ground the medieval and Baroque town has long since taken over.
Wallsee sits right on the boundary between Lower and Upper Austria, at the northern edge of the Mostviertel, the country of perry and cider. Old pear trees line the lanes and stand in the meadows around the farmsteads, white with blossom in April, and the region has signposted a Moststraße, a road of cider taverns and farm shops. A little downstream, the Danube enters the Strudengau, a narrow wooded gorge where whirlpools and rocks once terrified boatmen; Grein, with its castle and tiny old theatre, is the main town there.
For riders, the roads on the south bank wind through the rolling Mostviertel hills between farms and orchards, with gentle curves, good surfaces and little traffic. Cross the river at the power station or by ferry and the north bank opens up the Strudengau and the climbs into the Mühlviertel, with tighter bends and forest. On summer weekends you will share the riverside roads with many cyclists, and some sections have low speed limits. Spring blossom and the colours of October are the high points.
Perg, on the north side, is the nearest town of five thousand people and has fuel and shops; Amstetten, to the south, is larger. Wallsee itself has a few inns and cafés, and a glass of Most with a Brettljause, a board of cold meats, cheese and spreads on dark bread, is the local answer to a long day in the saddle. The castle is private, but its silhouette over the river at sunset is free for everyone.
