By Train from Stuttgart Airport to Ulm (Fastest & Most Recommended)
Taking the train is overwhelmingly the best choice for this route, offering an ideal balance of speed, frequency, cost, and convenience. The journey involves one simple transfer at Stuttgart's central hub.
Step-by-Step Guide
- Airport to Stuttgart Hauptbahnhof (Main Station):
- Option A (S-Bahn): From the STR airport terminal (Level 1), follow signs to the “S-Bahn”. Take S-Bahn Line S2 or S3 towards “Schorndorf” or “Backnang”. The ride to “Stuttgart Hauptbahnhof (tief)” – the underground station – takes about 27-30 minutes. Runs every 10-20 minutes.
- Option B (Shuttle Bus & Regional Train): A dedicated shuttle bus (Airport-Express) runs to “Filderstadt Bf” station (15 mins), where you can catch a regional train to the main station. Slightly faster overall (40-45 mins total) but less frequent.
- Transfer at Stuttgart Hauptbahnhof: From the underground S-Bahn platforms, take escalators/lifts up to the main hall. Find the platforms for long-distance and regional trains (track 11-20 are common for Ulm services). The transfer is well-signed (“Ulm” direction). Allow 10-15 minutes for the connection.
- Train to Ulm Hauptbahnhof: Board a Regional-Express (RE) train towards Ulm, Lindau, or Oberstdorf. Key train lines include RE 5 and RE 9. The direct journey from Stuttgart Hbf to Ulm Hbf takes approximately 55-70 minutes. No high-speed ICE train is needed for this short route; the RE is perfect and cheaper.

Money-Saving Tip: If traveling in a group of up to 5 people or on a weekend/day trip, the Baden-Württemberg-Ticket (from €25 for one person, €41 for up to 5) offers unlimited travel on regional trains (RE, RB, S-Bahn) throughout the state for a whole day. This can be significantly cheaper than individual tickets, especially for groups. Valid from 9 am on weekdays and all day on weekends.
By Long-Distance Bus (The Budget Alternative)
While there is no direct bus from Stuttgart Airport to Ulm, long-distance buses (Fernbus) offer the lowest cash fares, requiring a transfer to Stuttgart's central bus station. This option is ideal for flexible, budget-conscious solo travelers.
How It Works & What to Expect
- Get to Stuttgart's Bus Station (ZOB): First, you must reach Stuttgart’s Central Bus Station (Zentraler Omnibusbahnhof or ZOB), located next to the main train station (Hauptbahnhof). Take the S-Bahn (S2/S3, 30 mins) from the airport to “Stuttgart Hauptbahnhof (tief)” and walk 5 minutes.
- Catch the Bus to Ulm: Operators like FlixBus run multiple daily services from Stuttgart ZOB to Ulm (ZOB or sometimes near the main station). The bus ride itself takes about 1 hour 15 minutes to 1 hour 45 minutes.
- Arrival in Ulm: Buses typically terminate at Ulm ZOB (Einsteinstraße), which is a 10-15 minute walk or a short tram ride to the city center/cathedral area.
Bus Analysis: Pros, Cons & Key Data
- Cost: Fares are highly dynamic. Advance bookings can be as low as €4.99, while last-minute fares average €10-€20. Almost always cheaper than a standard train ticket.
- Total Travel Time: S-Bahn to ZOB (30 min) + wait + bus (75+ min) + walk in Ulm. Plan for at least 2 to 2.5 hours door-to-door.
- Frequency: Several departures daily, but less frequent than trains.
- Comfort & Amenities: Modern FlixBuses offer free WiFi, power outlets, and onboard toilets. Legroom is generally good.
- Luggage: Usually one large suitcase and one carry-on included in the ticket. Check the specific operator's policy.
Verdict: Choose the bus if your primary goal is to minimize cost and you don't mind a longer, two-part journey. Book online in advance for the best prices.
By Taxi or Private Transfer (For Special Circumstances)
This is the most expensive and least cost-effective option for the average traveler. A direct taxi from STR to Ulm is only recommended under specific circumstances due to the high cost and comparable travel time to the train.
Cost, Providers, and Considerations
- Estimated Cost: A pre-booked private transfer or taxi for this ~80 km (50 mile) journey typically costs between €180 and €250+, depending on the vehicle class, time of day, and exact destination in Ulm.
- Travel Time: Approximately 60-80 minutes direct, heavily dependent on traffic on the A8 autobahn.
- How to Book:
- Taxi Ranks: Available directly outside terminals 1, 3, and 4. Always confirm the approximate fare before departure.
- Private Transfer Services: Companies like Blacklane or KiwiTaxi offer fixed-price, pre-booked rides with meet-and-greet service. This is often more reliable and transparent than hailing a cab.
When Does a Taxi Make Sense?
- Late-Night/Early-Morning Travel: If your flight arrives or you need to depart outside of public transport operating hours (S-Bahn runs from approx. 4:30 am to 1:30 am).
- Large Groups (4+): Splitting the cost of a large van or minivan can sometimes be comparable to individual train tickets.
- Travelers with Significant Mobility Issues or Excessive Luggage: Door-to-door service eliminates all transfers and walking.
- Corporate Travel: When convenience and time billing outweigh cost considerations.
Expert Advice: For 95% of travelers, the train is superior. Only consider a taxi/transfer if you fit squarely into one of the above categories and the premium is justified.

Traveler Experience & Insider Tips

- Navigating Stuttgart Airport (STR): The airport is compact and well-signed in English. For trains, follow the green “S” signs for S-Bahn. The station is integrated into Terminal 1. If you have time, there are supermarkets (like Edeka) before security where you can buy cheaper water and snacks for the journey.
- The Stuttgart Hbf Transfer: This is a major station but is logically laid out. When you arrive via S-Bahn underground, look for signs to “Hauptbahnhof” or “RE/Zug” to reach the main hall. The main information board (Abfertigungstafel) lists all departures. Platforms for Ulm (Gleis) are usually in the 11-20 range.

- There are lockers (Gepäckschließfächer) at both Stuttgart Hbf and Ulm Hbf if you need to store bags and explore the city upon arrival/departure.
- Arriving in Ulm: Ulm Hauptbahnhof is centrally located. The magnificent Ulm Minster (Ulmer Münster) is a 10-minute walk straight out the front exit. The tourist information office is inside the station if you need a map.
- Connectivity: Free WiFi (WIFI@DB) is available on most RE trains and at major stations, though speed can be variable. Consider downloading your ticket and any entertainment offline.
