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 Riedenburg it runs 237 km to Riedenburg; allow about 3 h 44 of riding. On the way it passes Weltenburg‐Am Galget - Kleinkastell, Regensburg Großprüfening - Kastell und Vic, Straubing - Kastell St. Peter and back through Regensburg Großprüfening - Kastell und Vic. It was put together for the scenery rather than the shortest line.

1. Watchtowers WP 15/11 to 15/26 and fortlets
The Altmühl valley in Bavaria is one of Germany's best kept riding secrets, a winding river valley cut deep into Jurassic limestone, lined with juniper heaths, rock towers and castles. Near where the valley meets the Danube, the Roman frontier, the Raetian Limes, ran across the land, and the stretch of watchtowers and small forts numbered WP 15/11 to 15/26 lies in the wooded hills here, between Riedenburg, Dietfurt and the Danube town of Vohburg.

Planning note
Watchtowers WP 15/11 to 15/26 and fortlets is where the day begins. Next is Weltenburg‐Am Galget - Kleinkastell.
2. Weltenburg‐Am Galget - Kleinkastell
The Danube does something unexpected just upstream of Kelheim. Instead of wandering across flat Bavarian farmland, it cuts straight through a band of white Jurassic limestone, squeezed between cliffs that rise steeply from the water. This is the Weltenburg Narrows, and on the hill above the abbey at Weltenburg, at the spot called Am Galget, the Romans put a small fort to watch the river and the frontier.

Planning note
Weltenburg‐Am Galget - Kleinkastell comes up about 32 km into the recorded legs. Next is Regensburg Großprüfening - Kastell und Vic.
3. Regensburg Großprüfening - Kastell und Vic
There is not much to see at Großprüfening, and that is worth knowing before you arrive expecting walls. The Roman fort and its civil settlement lie on the western edge of Regensburg, close to where the Naab flows into the Danube, and what survives is mostly under fields and houses, known from excavation and aerial photographs rather than from standing masonry. The site is part of the Danube Limes, the river frontier that UNESCO listed in 2021, and its value is in the position: a garrison watching a river junction, a natural route north into what the Romans considered barbarian country.

Planning note
about 66 km into the recorded legs you reach Regensburg Großprüfening - Kastell und Vic. Next is Straubing - Kastell St. Peter, 38 km on.
4. Straubing - Kastell St. Peter
In 1950, workmen digging in a Straubing suburb found a hoard that stunned archaeologists: a collection of Roman parade armour, helmets with face masks and decorated metal pieces, buried in the third century, probably to hide them from invaders. The Straubing Roman treasure is now one of the most important finds of its kind north of the Alps, and it is displayed in the Gäubodenmuseum in the city. The fort at St Peter, on the eastern edge of town, was part of the same Roman presence. Straubing was Sorviodurum, a Roman town with several forts on the Danube frontier, and this was one of several forts there.
