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.
From Passau it runs 203 km to Passau; allow about 3 h 14 of riding. The stops in between: Oberranna - Kleinkastell, Hirschleitengraben - Wachtturm, Enns - Gräberstraße and back through Hirschleitengraben - Wachtturm. Expect gradients and long views.
Waypoint introductions and full write-ups
1. Passau Boiotro - Kastell
Passau stands at a meeting of three rivers, and the Romans noticed. The Inn, the Danube and the small, dark Ilz flow together under the cathedral hill, and the Inn bank opposite, where the Innstadt lies today, was the site of the Roman fort of Boiotro, which guarded the Danube frontier, the Limes, and commanded the river crossing. The name suggests the Boii, the Celtic people who once lived in this region, and the Roman fort stood in a long line of defences along the river, from here down to Oberranna in Austria.

Planning note
Passau Boiotro - Kastell is where the day begins. Next is Oberranna - Kleinkastell.
2. Oberranna - Kleinkastell
The Danube between Passau and Linz is one of the loveliest stretches of the whole river, and near Oberranna, on the Upper Austrian bank, it flows quietly between steep wooded slopes, dark and almost gorge-like. Here, beside the water, archaeologists found a small Roman fort, a Kleinkastell, part of the Danube Limes that guarded the northern frontier of the province of Noricum. Its remains are now protected under a modern shelter, and it forms part of the UNESCO listing of the Frontiers of the Roman Empire along the Danube.

Planning note
Oberranna - Kleinkastell comes up about 30 km into the recorded legs. Next is Hirschleitengraben - Wachtturm.
3. Hirschleitengraben - Wachtturm
Just west of Linz, the Danube narrows and the steep, wooded slopes of the Kürnberger Wald rise from its southern bank. In the Roman period this river was the frontier of the empire, and the soldiers who guarded it built a chain of forts and watchtowers along the bank to watch for raiders crossing from the north. The Hirschleitengraben watchtower is one of these, a small Roman tower in a side ravine of the forest, part of the Danube Limes, which UNESCO listed in 2021 as one of the great frontiers of the Roman Empire. Its remains are modest, but the position, looking over the river toward Puchenau and the hills of the Mühlviertel, makes the purpose clear.

Planning note
about 73 km into the recorded legs you reach Hirschleitengraben - Wachtturm. Next is Enns - Gräberstraße.
4. Enns - Gräberstraße
Enns claims to be the oldest town in Austria, on the strength of a charter granted in 1212, but its roots go much deeper. Just outside the modern town lay Lauriacum, a Roman legionary fortress that housed the Second Italian Legion and grew into one of the most important places on the Danube frontier, with a civilian town, temples and, as the Gräberstraße name suggests, roads lined with cemeteries. The Romans buried their dead along the roads outside settlements, and excavations here have found hundreds of graves, stones and offerings. The site is part of the Danube Limes World Heritage listing.

Passau Boiotro - Kastell closes the day.
