Three-Rivers City Passau – The often-photographed old town peninsula between the Danube and Inn invites exploration with its famous landmarks and winding medieval streets. Artistic historical facades, imposing grand buildings such as St. Stephen's Cathedral, the Prince-Bishop's Residence, the Town Hall, and Veste Oberhaus reflect the prosperity brought by the three rivers – Danube, Inn, and Ilz – and the centuries-long center of spiritual and secular power!
From the main train station, cycle through the newer "street canyons" of the old town peninsula down to the Inn – to the Marienbrücke.
The bike route takes us in a loop through the medieval Passau Innstadt to the Roman Museum at the Boiotro Fort – a Roman highlight! The excavation site and museum make the world of the Romans in Passau tangible and provide key insights into the fascination of the "Danube Limes." Just let yourself be immersed ;-)
Tip 1: The bike racks are located in the direction of travel, seemingly behind the museum – so complete the Innstadt loop.
Tip 2: At the peak of the Innstadt loop, a short detour to the Church of St. Severin is worthwhile. Unfortunately, it is often locked.
"Mens sana in corpore sano" (= a healthy mind in a healthy body) – After the "mental" museum, the "physical" cycling fun begins. Briefly through an urban residential area, then, right after the railway crossing, we reach the tree-lined Danube bank. It's worth taking a detour to the water in the small park-like area – a wonderful view of the three rivers of Passau! The Inn, Danube, and Ilz can be beautifully distinguished by their different water colors. Did the watchmen of the nearby Boiodurum fort also ponder this play of colors?
We leave the Roman settlement area and follow the Danube Limes downstream – partly through quaint riverside forest, partly through urban commercial areas. At the municipal sewage treatment plant, a sign points to the excavation site of the "Roman Watchtower." This was part of the watchtower chain along the Danube Limes. Unfortunately, due to its location in an operational area, it can only be visited with prior arrangement. Tip: A model of this watchtower in the Roman Museum at Boiotro Fort illustrates its function.
With the border crossing into Austria, the landscape becomes more natural: We cycle into the deeply carved Danube Gorge of the "Upper Danube Valley" – one of the longest breakthrough valleys of the Danube at over 90 km! The steep southern bank is characterized by spruce forests, while the inaccessible steep slopes of the northern bank have preserved the last (!) large slope and gorge forests of Central Europe. The valley floor is filled by the mighty Danube. No wonder this valley was designated a European protected area! The comfortable bike path generally follows the Nibelungenstraße due to space constraints. Occasionally, it goes over small side roads across one of the few alluvial terraces. Enjoyably cycling downstream, breathtaking Danube and valley flank views, narrow passages, alluvial terraces, and castles fuel the spirit of discovery. In the flow of Danube cycling, the natural protective effect of the wide Danube becomes apparent – a wet Limes. Just as rest stops were important components of the Roman road network, so today Roman rest areas line the bike path. They offer various insights into Roman life: Danube border, customs, early Christianity, etc. A bit further, the mighty Jochenstein Power Plant impresses. It is essentially a tribute to Roman engineering: surveying technology, opus caementicium (Roman concrete), aqueducts, water wheels, mill wheels, etc. come to mind. It's amusing to realize that Roman concrete sometimes lasts longer than modern concrete ;-). Shortly after the power plant, a replica of a Roman milestone reminds us of the Roman road running nearby. It was not only an important military and trade route but also the retreat route for the last Romans of Passau on their way to Lauriacum (Enns).
The charming Danube market in Engelhartszell invites you to pause – almost at the midpoint of the stage. The historic facades in the town center tell of prosperity as a medieval toll station. The local Engelszell Monastery is famous for its breathtaking abbey church – a Rococo jewel of Austria! Tip: It’s a must-see. Afterward, the terrain gets hillier. The manageable ascents are rewarded with enjoyable descents. Next stop: "Burgus Oberranna" – a Roman highlight! A protective structure allows you to experience the excavation site of a unique Quadriburgus in Austria up close. It also shows that this fortification of the Danube Limes was by no means just a minimalist utility building. Lifestyle, a Roman fundamental right.
The final stretch of this stage continues to be hilly. Passing the old ferry point Wesenufer, we head to the final highlight – the famous natural wonder Schlögener Danube Loop and the Roman Park Schlögen! Here, the Danube changes its flow direction twice within a few kilometers by nearly 180°. The Romans recognized the strategic potential and built a fort (100 – 150 men) and a port at the first bend. The excavations in the Roman Park bring this fortification and life within it closer. A grand finale!

Attention! Cross the border between Upper Austria and Bavaria at Passau. Don't forget your passport!
Additional information:Tip: If you don't know the splendour of Passau, you should at least make a detour to the cathedral on this route! Little known today: the old town peninsula was already a valuable settlement area thousands of years ago - it offered excellent trading opportunities due to the confluence of the three rivers, is flood-proof due to its elevated position and offered natural protection as a peninsula. Before the Romans, the large late Celtic settlement of Boiodurum was located here (the centre was on the Domberg). The Celts abandoned it around 50 - 30 BC for reasons that are still unknown. The Romans occupied what is now Passau around 50 AD and built a small fort at the centre of Boiodurum. A flourishing civilian settlement and Danube harbour developed in the surrounding area. At this time, relations with the free Germanic tribes were relatively relaxed. If you look back from the Marienbrücke bridge, you can easily recognise the elevated position of the peninsula, including the Domberg and the Ortsspitz.
With the crossing of the Inn, we not only move from the Roman province of Raetia to the province of Noricum, but also from the Gallic customs district (Atlantic - Inn) to the Illyrian customs district (Inn - Black Sea). This meant that inland customs duties had to be paid for transfer goods. This could be a lucrative business for the tenants of the customs stations. No wonder, then, that customs officers did not have the best reputation! Around 90 AD, the threat situation intensified and the Danube Limes was expanded. Here on the southern bank of the Inn, at the mouth of the Inn into the Danube, a second fort (300 soldiers) measuring around 14,000 square metres was built together with a surrounding civilian settlement. This took on the name Boiodurum.
From the middle of the 2nd century, a third, larger fort (1,000 soldiers) was built on the peninsula - Batavis. The Roman base grew steadily into an important shipping, transport and trading centre.
The Roman Empire began to crumble for the first time in the middle of the 3rd century: Internal battles weakened the empire and the Germanic tribes increasingly invaded the provinces. During this time, the Alemanni destroyed the two forts on the peninsula (Batavis + Ortsspitz), the fort on the southern bank of the Inn (Boiodurum) and the associated civilian settlements. The result: a reorganisation of the border defence! The number of troops in the forts was reduced, but quickly available auxiliary troops were installed in the hinterland. The forts were reduced in size but reinforced. Alternatively, the civilian settlements were relocated to the forts - fortified towns were born. Thus, at the end of the 3rd century, the massive fortress town of Batavis was built on the peninsula and the small castle-like fort of Boiotro on the southern bank of the Inn. Incidentally, Boiotro is a diminutive of Boiodurum. Well, the Romans also liked to joke.
In 476 AD, the Roman Empire collapsed with the deposition of the last Roman emperor, Romulus Augustulus. The Germanic tribes followed suit and took over supremacy. A world power full of light and shadow faded.
Severinus was active during this time of collapse. The Roman missionary had a small monastery built in Boiotro. The church of St Severin, not far from the fort of Boiotro, was probably built on its foundations. When Batavis could no longer be held militarily, he organised the retreat of the Roman population to Lauriacum (Enns). He was later canonised for his deeds.
Tip: Severinus of Noricum offers us very personal video insights into his turbulent times in three selected places!

We have no intention of concluding a contract with the users of this website. The utilisation of the data does not lead to the establishment of a contract with us.
The data may only be used for private use; any commercial use is prohibited. In particular, it is not permissible to offer the data on commercially run websites, file-sharing platforms etc. or to use it to develop commercial products. Downloading data does not imply that users are granted rights to the data concerned.
The tour recommendations posted were created with utmost care; nevertheless, we assume no liability for the correctness and completeness of the information.
We point out that neither the tour recommendations included on this website nor the associated data and information were posted by us, but rather by third parties (Art. 16 Austrian E-Commerce Act). We have no influence on whether the details provided (e.g. distance, level of difficulty, change in altitude, description etc.) are authentic, correct and complete. We do not review these third-party contents. For this reason, we assume no liability for the authenticity, correctness and completeness of the information.
Construction-related measures or other influences (e.g. landslides and similar occurrences) can lead to temporary or permanent changes in a route (e.g. loss of a bridge and similar occurrences). Such occurrences can lead to part of the route or the entire route becoming impassable.
The use of the data as well as undertaking (riding, walking, taking etc.) the recommended tours or using the network of paths occurs at users’ own risk and on their authority. In particular, users themselves are responsible for the choice of route, outdoor orientation, adherence to traffic rules, supplies and equipment for tours listed in Point 1 (e.g. bicycle etc.), wearing a helmet, estimating their own fitness, recognising dangers and maintaining an appropriate velocity. We exclude ourselves from any liability whatsoever for damages, in particular accidents, that occur whilst taking part in the recommended tours.
2.Some of the tours lead over roads with normal traffic conditions. Please observe that there is an increased risk which can be avoided by means of appropriate attention and proper estimation and implementation of one’s own abilities. For this reason, please travel a route that is unfamiliar to you slowly and with special care. Pay constant attention to potential dangers and always observe traffic. Do not leave the routes featured in descriptions.
The potential use of private roads, in particular forestry roads and agricultural transport roads, can be subject to legal restrictions, which must be observed and adhered to.
The normal traffic rules apply. Each user (e.g. biker, motorbiker) is responsible for adhering to these rules and maintaining his/her bike/vehicle and its equipment (lights, brakes etc.) in good working order. Each user is also responsible for ensuring that he/she rides at a velocity that is appropriate for the conditions and his/her skill level and for maintaining sufficient distance to the rider in front. We explicitly recommend adjusting velocity to correspond to the respective field of vision, wearing a helmet, using reflective clothing (or similar) and employing bicycle lights in line with regulations.
3.Each tour requires good physical fitness as well as detailed planning. We explicitly recommend only taking the tours in the case of optimal healthiness.
We recommend that you conclude an accident and liability insurance policy. Use an onboard computer that displays the respective kilometres travelled per day and is calibrated for the front wheel.
4.Special for mountain bikers – Fair-play rules:
Mountain biking is one of the most wonderful outdoor leisure-time activities. Whilst biking or on a mountain biking tour, mountains and lakes, meadows and cabins are re-discovered in new ways. A couple of rules for fair play in the forest help to avoid conflicts whilst mountain biking.
a.Pedestrians have the right of way: We are accommodating and friendly to pedestrians and hikers. Upon encountering these fellow travellers, we alert them by using the bicycle bell and slowly overtake them. We avoid paths with heavy pedestrian traffic altogether. Take nature into account: We do not leave refuse behind.
b.The braking distance should be half of the total distance visible: We ride at a controlled pace, are ready to brake and maintain a braking distance half as long as the total distance visible, especially in curves, because we always have to count on obstacles on the path. Damage to the path, stones, branches, wood piles, grazing livestock, cattle grids, barriers, tractor-type forestry machines and authorised vehicles pose dangers that we need to be ready for.
c.Don’t drink and drive!: Do not drink alcohol when mountain biking. Take care at stop-off points (dealing with bike racks, dirty shoes or clothing).
It is obligatory to provide first aid!
d.Marked routes, closed paths and blockades: Keep to the marked routes, observe the blockades and accept that these roads are primarily for agricultural and forestry use!
Blockades can often not be avoided and are in your own interest. Biking beyond the intended path and outside of opening times is punishable and turns us into illegal bikers.
e.We are guests in the forest and behave accordingly, including vis-à-vis forestry and hunting staff. Whilst mountain biking, mobile telephones and music players are forbidden! Biking requires your full attention.
f.Avoid unnecessary noise. Out of consideration to the animals living in the wild, we only bike during full daylight. As a principle, we always wear our helmet (even when riding uphill)! Don’t forget emergency supplies: We always have a repair set and bandages along.
g.Don’t overestimate your skills: We should not overdo it when it comes to biking technique and physical fitness. Take the level of difficulty posed by the route into consideration and make a precise estimate of your experience and skills as a biker (braking, bell, lights)!
h.Close gates: We approach grazing livestock at a walking pace and close every gate behind us. We should avoid causing escape and panic reactions in the animals. Nothing stands in the way of the fun and athletic challenge in the mountains and forests!
i.Traffic rules: The general traffic rules (StVO) apply for all the mountain biking routes and we adhere to them. Our bike therefore needs to be in perfect technical condition and equipped in line with the traffic rules, including brakes, a bell and lights. We inspect and service our mountain bikes regularly anyway.
