Augsburg to Konstanz: Ultimate Road Trip Guide

Did you know that the Via Claudia Augusta, the ancient Roman road that once connected the Po Valley to Augsburg, passes near this very route? For centuries, travelers have moved between these two poles, and today you can cover the distance in about 2 hours and 15 minutes without traffic, via the A8 and A96 autobahns, with a final stretch on the B31 into Konstanz. The total distance is approximately 220 km (137 miles), with the route gently undulating through Bavarian plains, rolling hills, and the Allgäu region before dropping to the shores of Lake Constance.

This guide answers the key questions: best stops Augsburg to Konstanz, how long to drive Augsburg to Konstanz, and is it worth driving Augsburg to Konstanz? Spoiler: yes. You’ll want to know how to find the best stops and hidden gems between cities.

The route begins on the A8 from Augsburg to exit 75 (Memmingen), then merges onto the A96, and finally leaves the autobahn at Wangen to take the B31 along the northern shore of Lake Constance. As you drive, expect slight topographical shifts: from flat farmland to gentle hills in the Allgäu. Fuel costs for the full trip, based on a typical mid-size car consuming 7 liters/100 km and fuel at €1.80/L, would be around €27.70 each way.

• Fuel Stations: Frequent along A8 and A96 (Shell, Aral, Total, etc.), with Autobahn rest stops every 20-30 km. On B31, stations are less common but available in larger towns like Lindau and Friedrichshafen.
• Topography & Efficiency: The route is mostly flat or rolling; speed variations cause slight efficiency drops. The A8 is largely straight, but the B31 has many curves and slower speeds, which can improve fuel economy if you drive steadily.
• Electric Vehicles: Charging stations are available at major rest stops (e.g., Tesla Superchargers near Memmingen) and along the B31 in towns.

Specific road names: A8 (Augsburg–Memmingen), A96 (Memmingen–Wangen), B31 (Wangen–Konstanz). Toll-free – German autobahns have no tolls for passenger vehicles. Expect average speeds of 130 km/h on the autobahn and 80-100 km/h on the B31.

As you leave Augsburg, the terrain opens into the Bavarian Swabia countryside, with wide fields and small forests. Near Memmingen, you enter the Allgäu region, known for rolling hills, dairy farms, and views of the Alps on clear days. The final stretch along the B31 hugs the northern shore of Lake Constance, offering glimpses of the lake and the Swiss and Austrian Alps across the water.

• Natural Highlights: The Allgäu – look for the Iller River valley near Memmingen; Lake Constance shoreline between Lindau and Konstanz.
• UNESCO Sites: The Prehistoric Pile Dwellings around Lake Constance (several locations near the route, e.g., in Uhldingen-Mühlhofen, about 30 km before Konstanz). A short detour to the Pfahlbauten museum is highly recommended.
• Climatic Conditions: The Allgäu can have sudden rain showers even in summer; the lake region is known for the 'Föhn' wind, which brings warm, clear conditions and stunning sunsets. Best sunset views: at the lake near Immenstaad or Meersburg.

Culinary stops: Eglingen near Ulm has a traditional Gasthof with Swabian Maultaschen. In Kißlegg (Allgäu), stop at Dorfwirtschaft for Allgäuer Kässpätzle. On the B31, Meersburg has multiple lakeside restaurants serving fresh Bodensee fish. Local commerce: roadside stalls sell Allgäu cheese, honey, and schnapps near Wangen; in the Vogelhäusle area (near Friedrichshafen) you can buy Zwetschgen (plum) products.

Cultural tips: the region is predominantly Bavarian and Swabian; patience is appreciated at farm stands. Many villages have weekly markets (e.g., Lindau on Wednesdays and Saturdays). Good times to stop for photos: around 10:30 AM for the Allgäu morning light, or 5:30 PM for lake sunsets.

Road quality on the A8 and A96 is excellent – smooth asphalt, clear markings, and good night illumination from high-mast lighting. The B31 is well-maintained but has some sections with tighter curves and no central barrier; watch for cyclists and pedestrians in lakeside towns. Speed cameras are frequent on the B31.

• Safety Tips: Stay in the right lane on the autobahn unless passing. On B31, beware of tailgating: slower traffic is common in summer. Rest areas have surveillance, but never leave valuables visible.
• Fatigue Management: Recommended rest zones – Autobahnrasthof Allgäu (km 50 on A96) with a quiet petrol station and shaded benches; also the rest area near Wangen (B31) has a park-like setting perfect for a short nap.
• Family-Friendly Stops: Legoland Deutschland (Günzburg, 30 min detour from A8); Allgäu Skyline Park in Rammingen (directly off A96); on the B31, the Ravensburger Spieleland in Meckenbeuren is a paradise for kids.

Pet-Friendly Framework: Most Autobahn rest stops have designated 'Dog Toilet' areas and some grass patches. In Kißlegg, the Allgäuer Erlebniswelt (a camping park) is dog-friendly and offers a dog beach. Along the B31, there are several 'Hundestrand' (dog beaches) near Langenargen and Kressbronn. Cafés like Café Seestern in Meersburg allow dogs on their terrace. Bring water and waste bags.

Hidden Off-Route Spots: Just 5 minutes off the A8 at exit 77 (Buxheim), you can find the abandoned Buxheim Monastery (partly ruin, peaceful garden). Near Kißlegg on the A96, the small village of Immenried has a charming old mill and a quiet chapel. On the B31, a short detour to the ruins of 'Burg Heimegg' near Hagnau gives a great lake view without tourist crowds.
