Blois to Pau Road Trip: History, Landscapes & Hidden Gems

Driving from Blois (Loir-et-Cher) to Pau (Pyrénées-Atlantiques) covers roughly 550 km via the A85, A20, and A62 motorways – a journey that takes about 5–5.5 hours without stops. This route traces the gradual transition from the gentle Loire Valley to the rugged foothills of the Pyrenees.

One of the most interesting stretches is the section near Vierzon, where the A20 crosses the ancient Roman road Via Agrippa. This exact corridor has been used for centuries as a north-south artery, connecting the royal heartland to the Spanish borderlands.

Family and Child Suitability: The A20 has several child-friendly stops. The 'Aire de la Vallée de la Creuse' (km 230) features a playground and a small petting zoo. Near Brive, the 'Parc de la Brousse' offers a treetop adventure course.

• Interactive museum: 'Cité de l'Écrit' in Montmorillon (exit 43), where kids can try medieval writing.
• Park: 'Jardin de l'Évêché' in Limoges, with a maze and duck pond.

Pet-Friendly Framework: Most rest areas on A20 allow dogs on a leash. Specifically, 'Aire de la Couarde' (km 280) has a designated dog walking area with waste bags. Several restaurants along the route, such as 'Le Relais de l'A20' in Uzerche, welcome pets on the terrace.

• Tip: Look for 'Chiens admis' signs. The hotel 'Campanile Limoges Nord' accepts dogs for a small fee.

Fatigue Management & Rest Zones: Strategic rest areas include 'Aire de l'Occitanie' (A20, km 210) – 24/7, clean toilets, and a dedicated nap zone. Another is 'Aire de la Loue' (A62, km 160) with shaded parking.

• Recommended quick nap spot: 'Aire de l'Arbresle' (A20 km 190) – quiet, low traffic, with benches.
• For longer breaks, exit at Limoges city center and park at 'Parc de la Borie' – green space with free parking.

Hidden Off-Route Spots: For those wondering how to find the best stops and hidden gems between cities, how to find the best stops and hidden gems between cities offers strategies. Some gems include:

• Abandoned Château de la Mothe (near A20 exit 38) – 5 min from highway, a 12th-century ruin with panoramic views.
• Village of Saint-Benoît-du-Sault (exit 37) – classified as one of France's most beautiful villages, with a Romanesque church.
• Secret waterfall: Cascades d'Autoire (near A20 exit 45, 10 min detour) – stunning 30m waterfall in the Dordogne valley.

Climatic Conditions & Route Aesthetics: The A20 corridor experiences a mix of oceanic and continental climate. In autumn and spring, morning fog is common between Limoges and Brive, reducing visibility. The Mistral wind can affect the A62 near Toulouse, but leeward of the Pyrenees, Pau enjoys a microclimate with more sunshine.

• Best time for views: Late afternoon, when the sun lights up the limestone cliffs near Carennac.
• Wind alert: The A62 between Montauban and Pau can have strong crosswinds; consider a lower speed.

Geographical Shifts: From Blois (60m altitude) you descend into the Sologne forests, then climb onto the Limousin plateau (300m), cross the Dordogne River valley at 150m, and finally reach the Pyrenean foothills at Pau (200m). The scenery changes from château-studded plains to granite hills, then limestone gorges, and finally vineyards backed by snowy peaks.

• Key viewpoint: A20 northbound, just south of Limoges – panoramic view over the Lac de Vassivière.
• Best sunset spot: Rest area of Caussade (A20 southbound, km 210) with views over the Tarn valley.

UNESCO World Heritage Sites: Within a short detour from the A20, the medieval town of Albi (Episcopal City) is a 20-minute detour from the A20 at exit 43. Saint-Émilion (Jurisdiction of Saint-Émilion) is reachable via a 30-minute side trip from the A89 near Libourne.

• Albi: Sainte-Cécile Cathedral and the Berbie Palace.
• Saint-Émilion: Monolithic church and underground catacombs.

Culinary Infrastructure: The route is dotted with regional diners. Near Vierzon, 'Le P'tit Creusois' serves traditional potato-based dishes. In Limoges, stop at 'Bistrot Limousin' for duck confit. For a quick bite, the A20 rest area at 'La Bussière' has a bakery with local pastries.

• Regional specialties to try: Trouffiat (Limousin potato cake), Jambon de Bayonne (near Pau), and Côtes de Gascogne wines.
• Roadside stalls: Near Montauban, vendors sell fresh foie gras and Armagnac.

Local Commerce and Culture: The A20 corridor is famous for its pottery villages. At exit 46 (La Souterraine), you'll find artisan potters selling traditional Limoges-style ceramics. For authentic regional goods, stop at the weekly market in Brive-la-Gaillarde (Wednesday/Saturday mornings).

• What to buy: Hand-painted porcelain (Limoges), walnut oil (Périgord), and Basque linens (Pau).
• Visit: Maison de la Porcelaine in Limoges (off A20 exit 35).

Fuel and Route Economics: The A85 and A20 are mostly toll-free except for the A62 section. Total toll cost for a standard car is approximately 25–30 EUR. Fuel stations are abundant every 20–30 km on the A20; however, on the A85 near Châteauroux stations are sparser – fill up at Blois or Vierzon.

• Estimated fuel cost: 55–70 EUR (petrol) / 45–60 EUR (diesel) for the 550 km trip.
• Fuel efficiency tip: Maintain 110 km/h on A20 to save 10-15% fuel compared to 130 km/h.
• Station density: good on A20 (every 20 km), moderate on A85, excellent on A62.

Road Quality and Safety: The A85 is in very good condition, well-lit with reflective markings. The A20 between Vierzon and Brive is a modern 2x2 lane with hardened shoulders. Night illumination is present on most sections except some rural A20 stretches; use high beams where allowed.

• Toll gates: Only on A62 (Toulouse–Pau), accept credit cards and electronic tolling.
• Road surface: Smooth asphalt, occasional repairs near Limoges.
• Safety tip: Watch for deer crossing signs near Argenton-sur-Creuse, especially at dawn/dusk.
