Colmar to Quimper Road Trip Guide: Full Route Breakdown

The route from Colmar (48.0796° N, 7.3585° E) to Quimper (48.0003° N, -4.0968° W) spans approximately 950 kilometers, crossing from the Alsatian wine country to the wild coast of Brittany. Unlike the direct A4/A85 corridor, the most scenic path follows the D83 south from Colmar, then the A36 west, merging onto the A6 near Beaune, then A10/A28 through the Loire Valley, finally attaining the N165 near Nantes for the final Breton leg. A distinct driving quirk: the D83 runs parallel to the Rhine-Rhône canal, and you'll notice Sud-Aviation's abandoned factory hangars between Colmar and Sélestat, a remnant of France's aerospace history.

The complete drive typically takes 9-10 hours without stops. However, as detailed in how to find the best stops and hidden gems between cities, the journey is best stretched over three days to absorb the cultural and geographical diversity. The route passes through six distinct regions: Alsace, Burgundy, Centre-Val de Loire, Pays de la Loire, and Brittany. Below is a summary table of the route segments.

Fuel and Route Economics

Fuel costs for the 950 km journey depend on vehicle efficiency. At €1.85/L for diesel (April 2025 average) and a consumption of 6L/100km, the total fuel cost is approximately €106. Petrol vehicles at 8L/100km would run closer to €140. The topography is mostly flat east of the Vosges but includes rolling hills in Burgundy (Côte-d'Or) where fuel efficiency dips. Fuel stations are abundant along the A36, A6, and A10, with stations every 30-40 km. In Brittany, the N165 has fewer services; fill up in Rennes. For maximum efficiency, maintain 110 km/h on highways and avoid air conditioning in open-window-friendly stretches.

Road Quality and Tolls

• Surface condition: excellent on A-routes (A36, A6, A10, A11, A85); N165 is good but older sections near Quimper can be uneven.
• Toll gates: A36 (€10.20), A6 (€25.40), A10 (€18.90), A11 (€12.30) – total approx €67 for the entire highway route. The D83 from Colmar to Mulhouse is free.
• Night illumination: fully lit on autoroutes; N165 has sections unlit – use high beams where safe.
• Safety tip: in Alsace, watch for cyclists on D83; in Brittany, frequent 90 km/h zones with speed cameras.

UNESCO World Heritage Sites

Three UNESCO World Heritage sites lie along or within a 20-minute detour. 1) The Historic Centre of Strasbourg (Notre-Dame Cathedral) – 70 km north of Colmar, but worth a detour. 2) The Climats of Burgundy in the Côte de Nuits – actually the vineyards themselves, but the town of Beaune (Hospices de Beaune) is a tangible cultural monument. 3) The Loire Valley between Sully-sur-Loire and Chalonnes – specifically the Château de Chenonceau (35 km west of Tours). No UNESCO sites in Brittany on the direct route to Quimper, but the Mégalithes of Carnac (110 km south) are a significant detour.

Family and Child Suitability

Interactive stops abound: 1) Le Petit Train de la Mine (Wangenbourg) – 20 min off D83, a coal mine tour with underground train (€12/child). 2) Futuroscope (Poitiers) – near the A10, a multimedia park with 4D attractions (€36/adult). 3) Océarium du Croisic (near Nantes) – a large aquarium with touch pools (€14/child). All have dedicated parking and changing facilities.

Pet-Friendly Framework

Most rest areas allow dogs on leash. Notable stops: Aire de Beaune-Merceuil (A6) has a fenced dog park. Aire de Loire-Angers (A11) has shady picnic spots with water bowls. In Brittany, the Aire de la Rance (N165) provides open grass. The how to find the best stops and hidden gems between cities guide suggests filtering for pet-friendly tags on Wayro.

Fatigue Management & Rest Zones

• Aire de l'Étang (A36, near Belfort) – quiet, with wooden shelters, ideal for a 20-min nap.
• Aire de la Côte-d'Or (A6, km 186) – shaded benches and a short forest trail.
• Aire de la Mothe-Saint-Héray (A10, km 245) – low traffic rest area with vending machines.
• Aire de Brocéliande (N165, near Paimpont) – named after the legendary forest, a calm spot to stretch.

Hidden Off-Route Spots

• Village de la Route du Vin (Riquewihr) – 5 min east of D83 exit 23, a medieval village with cobbled streets (€5 parking).
• Château de la Rochepot (5 min from A6 exit 24) – a 13th-century castle with polychrome roofs.
• Les Caves de la Perrière (A28, exit 12) – a tiny hamlet with a troglodyte bakery selling fresh bread.
• Chapelle Sainte-Anne (N165, exit 14) – a 15th-century chapel atop a granite hill with views of the Odet valley.

Geographical Shifts

Departing Colmar, the Vosges foothills give way to the Alsatian plain – orchards and vineyards terraced on the lower slopes. At Mulhouse, industry dominates, but quickly the terrain flattens into the Burgundy plateau. South of Beaune, the landscape rises gently into the Côte-d'Or hills, where neat rows of Pinot Noir vines stretch to the horizon. After the A6 merges with the A10 near Orleans, the Loire Valley opens up: wide river, châteaux, and poplar-lined roads. The final leg, N165 through Brittany, is characterized by granite outcrops, heathland, and eventually the coastal rias near Quimper.

Best Stops for Natural Views

• The Ballon d'Alsace (1,247 m) – a 15-minute detour from Colmar on the D466, offers panoramic views of the Vosges.
• Parc naturel régional du Morvan – cross the A6 at Avallon for a short hike; the Cascades de la Canche are stunning after rain.
• Troglodyte vineyards of Saumur – from the A85 take exit 4 for a view of caves carved into the tuffeau cliffs.
• La Roche aux Fées (The Fairy Rock) – a Neolithic dolmen near Essé, 10 minutes off the N165 between Rennes and Quimper.

Local Commerce and Delicacies

• Alsace: kugelhopf cakes and Gewürztraminer wine – stop at Cave de Turckheim on the D83.
• Burgundy: Dijon mustard (Maille boutique in Dijon, exit 24 on A6) and jambon persillé.
• Loire Valley: goat cheese (Sainte-Maure de Touraine) and rillettes from Tours – market at Place de la Cathédrale.
• Brittany: galettes de sarrasin (buckwheat crêpes) and cidre bouché – at the Quimper market (Place Terre-au-Duc).
