Passau sits on a narrow spit of land at the point where three rivers meet, right on the Austrian border in the far south east of Bavaria. The Danube arrives from the west, the Inn from the south out of the Alps, and the small dark Ilz from the north out of the Bavarian Forest, and for a stretch below the old town you can see three different colours of water running side by side before they mix.

What Is Here
THE DREIFLUSSECK IS THE POINT OF THE PLACE AND THE THREE COLOURS ARE REAL. The hero image is the aerial. The Inn runs pale green-grey with alpine glacial sediment, the Danube a browner blue, and the Ilz almost black with peat from the forest. Walk to the tip of the spit, which is a public park at the end of the old town, and you can watch the seam between them. It is clearest after dry weather; in flood it is all one brown river.
AND THE FLOODS ARE NOT A FOOTNOTE HERE, THEY ARE THE TOWN'S BIOGRAPHY. Three rivers converging on a narrow point produces the highest flood risk of any German city of its size. IN JUNE 2013 THE WATER REACHED ABOUT 12.89 METRES, the highest since 1501, and the old town was evacuated with boats in the streets. There was serious flooding again in 2024. THE HIGH-WATER MARKS ARE PAINTED UP THE WALL OF THE OLD TOWN HALL with their dates, and the 1501 line is above head height on the first floor. Go and look at them: it is the single most memorable thing in the city. IF YOU TRAVEL AFTER HEAVY RAIN OR A FAST ALPINE THAW, check the river levels, because high water closes the riverside paths, the boat trips and sometimes the lower streets.
ST STEPHEN'S CATHEDRAL HOLDS ONE OF THE LARGEST CHURCH ORGANS IN THE WORLD. The second image is it, green-domed and white. The instrument has roughly 17,900 pipes across five separate organs playable from one console, and THERE IS A SHORT ORGAN CONCERT MOST WEEKDAYS AROUND NOON FROM MAY TO EARLY OCTOBER, plus some afternoons. It costs very little, it fills the cathedral, and it is the best hour available in Passau. Check the current schedule, which varies by season and is suspended in winter.
THE VESTE OBERHAUS LOOKS DOWN FROM THE RIDGE ACROSS THE DANUBE. The third image is the fortress. The prince-bishops built it from 1219 to control a city that kept trying to govern itself, which tells you the relationship. There is a museum, and the BATTERIE LINDE viewpoint gives the classic shot of the whole spit with all three rivers. YOU CAN WALK UP IN ABOUT TWENTY-FIVE MINUTES, steeply, or take the seasonal shuttle bus from the Rathausplatz.
THE OLD TOWN IS ITALIAN BAROQUE AND THAT IS NOT AN ACCIDENT. After fires in 1662 and 1680 destroyed most of it, Italian architects rebuilt it, which is why a Bavarian border town looks like Salzburg's smaller cousin. The lanes are narrow, steep and largely pedestrian.
IT IS A UNIVERSITY TOWN AND A RIVER CRUISE PORT AT ONCE, so term-time evenings are lively and midday between April and October can fill with cruise groups and empty again by six.
AUSTRIA IS ACROSS THE WATER AND THE DANUBE CYCLE PATH STARTS HERE. The Donauradweg to Vienna is one of the most popular long cycle routes in Europe and Passau is its usual starting point, so expect loaded bicycles everywhere in summer.
When to Go
May to early October for the organ concerts, the boat trips, the river terraces and the cycle traffic.
September is the pick: concerts still running, cruise groups thinning, warm evenings.
Winter is quiet and cold with a small Christmas market in the cathedral square, and the organ concerts stop.
LATE SPRING AND EARLY SUMMER ARE THE FLOOD SEASON, because alpine snowmelt in the Inn coincides with Atlantic rain on the Danube. The 2013 flood was in June. That is not a reason to avoid those months, but it is a reason to check the levels rather than assume.
Getting There
By train, about two hours from Munich and two and a quarter from Nuremberg, with Vienna about three and a half hours east and Salzburg two hours south. The station is a ten minute walk from the old town.
By air, Munich at two hours is the usual gateway, with Linz in Austria closer but thinly served.
By car, on the A3. THE OLD TOWN IS LARGELY PEDESTRIAN and the lanes are too narrow to drive; park in a Parkhaus at the edge.
You do not need a car. The old town is small and steep, the fortress has a shuttle, and the river boats leave from the middle of town.
Is Passau Safe for Women?
Passau is a small, prosperous border city and is very safe. The FCDO publishes no advised-against areas anywhere in Germany, and its terrorism wording is the strongest it uses: terrorists are very likely to try to carry out attacks in Germany, with restaurants, MARKETS, shopping centres, places of worship, sporting events and crowded public spaces named as possible targets. That is worth knowing in a country where a Christmas market is often the reason for the trip, and the response is awareness rather than avoidance. On crime the FCDO puts German levels on a par with the UK and names theft and pickpocketing at airports, railway stations and in crowded places, with the specific advice not to leave bags unattended. It also gives one unusually concrete warning: exchange currency only at banks and legitimate bureaux, because counterfeit notes are passed to visitors at street kiosks.
THE WATER IS THE SERIOUS HAZARD AND IT IS SPECIFIC. Three fast rivers meet at a narrow point: the Inn in particular is cold, grey and moves far faster than it looks because it is alpine meltwater, and there are no swimming beaches in the city for that reason. THE RIVERSIDE PATHS AND THE SPIT ARE LARGELY UNFENCED. Do not swim at the confluence, where the currents converge and conflict.
FLOODING CAN CLOSE THE LOWER OLD TOWN AT SHORT NOTICE. If the levels are rising, follow the local instructions rather than going down to photograph it.
The lanes are steep, narrow and cobbled, with stepped alleys between the river level and the ridge, slippery in rain.
The climb to the Veste Oberhaus is steeper than it looks and the path is unlit at night.
Cycling is extremely heavy in summer because this is the start of the Danube route, and loaded touring bikes on a narrow riverside path stop slowly. Look before stepping sideways.
Ordinary urban care around the student bars at night, which are busy and unthreatening.
The Passau Packing List
River damp, steep cobbled lanes, a cold cathedral and changeable border weather.
Our merino base layers are 100% Australian merino at 17.5 micron, and a long sleeve merino wool base layer for women fits a town built on this shape: you climb to the fortress and arrive hot, sit still for an hour in a cold stone cathedral at the organ concert, and then walk a damp riverside in the evening. Wool is the one layer that is right in all three. From November to March add a heavyweight merino base layer.
A Columbia Fast Trek II fleece, which is worth having in the cathedral even in August, and a Marmot PreCip Eco rain jacket. This corner of Bavaria is wet and the rain arrives off the Alps quickly.
Walking shoes with grip and Darn Tough merino socks for the stepped alleys and the fortress climb, which is the steepest walking in this batch outside the Alps.
Not linked and worth packing: SOMETHING TO COVER YOUR SHOULDERS for the cathedral, which is a working church and where you may be sitting for an hour; A WATER BOTTLE for the climb; CASH, because the smaller Gasthauser and the river kiosks prefer it; AND A CHECK OF THE ORGAN CONCERT SCHEDULE AND THE RIVER LEVELS, which between them decide what a day here looks like. Germany is otherwise increasingly card-friendly.

Emergency numbers: 112 for police, ambulance and fire, free from any phone including a locked mobile, with operators who will find an English speaker. It is the single number across the whole European Union.
Three rivers converging on a narrow spit gives Passau the highest flood exposure of any German city of its size, and this is the town's defining fact rather than a caveat. IN JUNE 2013 THE WATER REACHED ABOUT 12.89 METRES, the highest since 1501, and the old town was evacuated; there was serious flooding again in 2024. THE HIGH-WATER MARKS ARE PAINTED UP THE OLD TOWN HALL WALL with their dates. LATE SPRING AND EARLY SUMMER ARE THE FLOOD SEASON, when alpine snowmelt in the Inn meets Atlantic rain on the Danube, so CHECK RIVER LEVELS after heavy rain or a fast thaw: high water closes the riverside paths, the boat trips and sometimes the lower streets, and if levels are rising, follow local instructions rather than going down to photograph it. THE INN IS ALPINE MELTWATER, cold and far faster than it looks, there are no city swimming beaches for that reason, and the paths and the spit are largely unfenced. DO NOT SWIM AT THE CONFLUENCE, where the currents conflict. ST STEPHEN'S CATHEDRAL has one of the largest organs in the world at roughly 17,900 pipes, with SHORT CONCERTS MOST WEEKDAYS AROUND NOON FROM MAY TO EARLY OCTOBER, suspended in winter: check the current schedule. The Veste Oberhaus is a steep twenty-five minute climb or a seasonal shuttle from the Rathausplatz, and the path is unlit at night. CYCLING IS EXTREMELY HEAVY IN SUMMER because the Danube cycle route to Vienna starts here. Austria is across the water, so carry ID.
US State Department travel advisory: the Germany advisory. Read the current level there directly rather than relying on a figure printed in any guide.
UK FCDO travel advice: gov.uk/foreign-travel-advice/germany, and read the safety and security page rather than only the landing page, because that is where the substance sits.
Main hospital: the Klinikum Passau on the Innstrasse has a 24 hour emergency department in the city. Dial 112 for police, ambulance or fire, and note that AN INCIDENT ON ANY OF THE THREE RIVERS goes through 112 to the water rescue service, the Wasserwacht, rather than to a land ambulance, which is the call from the riverside or the spit; the AUSTRIAN EMERGENCY NUMBER IS 112 TOO and 140 reaches Austrian alpine rescue if you have crossed the border. The overnight pharmacy rota is posted on every Apotheke door. Germany is in the EU, so a UK Global Health Insurance Card or an EU European Health Insurance Card gives you state-provided medically necessary care on the same terms as a resident. That is not the same as free: German healthcare involves patient contributions and the card does not cover repatriation or private treatment, so travel insurance sits on top of it. German hospitals are excellent and English is widely spoken in them, particularly in university cities. An Apotheke, marked with a red A, handles minor problems without an appointment and the duty rota for out-of-hours is posted in the window. Tap water is drinkable everywhere. Dial 112 for an ambulance and 116117 for the non-emergency medical service.

Takeaways
Go and read the high-water marks on the old town hall. The 1501 line is above head height.
Check the river levels after heavy rain or a fast thaw.
The noon organ concert from May to early October is the best hour here.
Do not swim at the confluence. The currents conflict.
Solo women safety assessment: Passau is a very easy place to travel alone. It is a small, wealthy border city of about 50,000 with a university, so the old town is lively in term time without being rowdy, the centre is small enough to cross in fifteen minutes, and eating alone in a Gasthaus or on a river terrace is completely ordinary. There is no district to avoid, and the student bars are busy and unthreatening. 112 REACHES POLICE, AMBULANCE AND FIRE free from any phone and works in Austria too, which matters because the border is across the water; the Klinikum Passau on the Innstrasse has a 24 hour emergency department in the city, and 140 reaches Austrian alpine rescue if you have crossed over. LEARN THE WATER ROUTE: trouble on any of the three rivers goes through 112 to the Wasserwacht water rescue service rather than to an ambulance, and that is the right call from the riverside or the spit. THE RIVERS ARE WHERE THE DANGER IS AND IT IS NOT OBVIOUS FROM LOOKING. The Inn is alpine meltwater, cold and moving much faster than its surface suggests, there are no swimming beaches in the city precisely because of that, and the riverside paths and the park at the tip of the spit are largely unfenced. Never swim at the confluence itself, where three currents meet and conflict. The other thing to respect is the flooding, which is this city's history rather than a hypothetical: the 2013 flood reached the highest level since 1501 and emptied the old town, there was serious flooding again in 2024, and late spring and early summer are the risky months. Check the levels after heavy rain or a fast alpine thaw, and if the water is rising do what the local notices say instead of walking down to see it. On foot, the lanes are steep, narrow and cobbled with stepped alleys between the river and the ridge, and the fortress path is unlit after dark.
Reading On
Passau is the downstream end of a Danube and Franconian group this library now covers together. The Regensburg packing list is an hour upstream and leads on the Steinerne Brucke and the Roman wall, which makes the two a natural river pair; the Nuremberg packing list leads on the castle and the Christkindlesmarkt and the Bamberg packing list on its undamaged old town and smoked beer. South and east, this is a border city: the Salzburg packing list is two hours away and the Vienna packing list is the far end of the cycle route that starts here. North west, the Munich packing list covers the Bavarian capital, and the Berchtesgaden packing list the alpine corner south of it. For the country, the Germany travel guide for women and the Germany packing list carry the rail network and the regions. For why wool suits a steep climb, a cold cathedral hour and a damp riverside evening in one shirt, read the guide to merino wool base layers for women. Every destination we cover is indexed at the travel packing guide for women, and the base layers are at the Roman Trail collection.
