Distance and timing basis
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 Künzing it runs 182 km to Künzing; allow about 2 h 47 of riding. The stops in between: Passau Boiotro - Kastell, Oberranna - Kleinkastell, Passau Haibach - Burgus and back through Oberranna - Kleinkastell. It crosses from Germany into Austria - carry ID and check vignette or toll rules.
Speed drops and stays down. Park rather than crawl through. 31 km through ground somebody thought worth listing. The road passes it rather than bypassing it.

1. Künzing - Amphitheater und Vicus
Künzing sits on the Danube in Lower Bavaria, in a broad, fertile plain known as the Gäuboden, and in Roman times it was a place with a name, Quintana. The Romans built a fort here in the second century, one of the posts on the river frontier of the province of Raetia, and a civilian settlement, a vicus, grew up beside it, with houses, workshops and even an amphitheatre. The Danube Limes in Germany, Austria and Slovakia was listed by UNESCO in 2021, and Künzing is one of the places where it is easiest to grasp what daily life along the frontier was like.

Planning note
Künzing - Amphitheater und Vicus is where the day begins. Next is Passau Boiotro - Kastell.
2. 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 comes up about 33 km into the recorded legs. Next is Oberranna - Kleinkastell.
3. 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
about 63 km into the recorded legs you reach Oberranna - Kleinkastell. Next is Passau Haibach - Burgus.
4. Passau Haibach - Burgus
Passau sits where three rivers meet, the Danube, the Inn and the Ilz, and from the high point of the Oberhaus fortress you can see their colours run side by side before mixing: green from the Inn, blue-grey from the Danube, and dark from the Ilz, which flows down from the Bavarian Forest stained by peat. The Romans knew this spot well. They had a fort here called Batavis, named after a unit of Batavian soldiers from the Rhine delta, and another at Boiotro across the Inn, and along the Danube downstream they built small fortified towers called burgi to watch the river and signal to each other. One of these late Roman burgi stood near Haibach, and its remains are part of the Danube Limes, inscribed by UNESCO in 2021 as part of the Frontiers of the Roman Empire.
