Siena to Arezzo Road Trip Guide: Tuscany's Scenic Drive

Departing from Siena's Piazza del Campo, the SS73 highway unfurls 75 kilometers northeast to Arezzo. This is no ordinary stretch: the road shadows the ancient Via Cassia, connecting two hilltop republics that once vied for Tuscan dominance. A lesser-known fact: the route crosses the Valdichiana, a valley drained by the Medici in the 16th century, transforming malarial marshland into fertile farmland—today the backbone of Chianina cattle country.

The drive typically takes 1 hour 15 minutes without stops, but the real question is: how long to drive Siena to Arezzo with exploration? Budget 4–6 hours to savor the detours. For deeper context on curating your own stops, consult how to find the best stops and hidden gems between cities.

The SS73 is predominantly a two-lane state highway, well-maintained with periodic passing lanes. Toll-free, unlike the A1 motorway which parallels to the west. Fuel stations are sparse after Buonconvento; fill up in Siena or near the Valdichiana exit. At time of writing, unleaded petrol costs about €1.85/liter. Toll roads are absent on this route, making it economically efficient for budget travelers.

For electric vehicles, charging points exist in Siena (several fast chargers at Coop Via Fiorentina) and Arezzo (Piazza della Repubblica). Mid-route, only Lucignano offers a single 22 kW AC charger at the municipal parking lot. Plan accordingly. Parking in Arezzo’s historic center costs €2/hour; free lots exist at the Stadio Comunale, a 10-minute walk to Piazza Grande.

• Best practice: Depart Siena after 9 AM to avoid school traffic.
• Warning: Sunday mornings see local markets blocking main squares.
• Coordinates: Siena (43.3188, 11.3313); Arezzo (43.4668, 11.8820).

The Valdichiana unfolds as a vast, flat basin ringed by gentle hills. This is Chianina cattle territory—the breed celebrated for bistecca alla fiorentina. As you drive south of Lucignano, the terrain rises into rolling vineyards (Vino Nobile di Montepulciano DOCG). A mandatory photo stop: the Crete Senesi near Asciano, a lunar landscape of clay hills and cypress rows, best viewed from the SP46 turnoff at 43.2361° N, 11.5611° E.

Local commerce thrives in medieval borghi. Buonconvento’s Coop supermarket sells local pecorino and salumi. Lucignano’s weekly market (Wednesday mornings) offers handmade ceramics and linens. For olive oil, head to Frantoio Carioti in Foiano della Chiana—they offer tastings by appointment. Arezzo’s antiques market (first weekend monthly) spills through Piazza Grande, a must for collectors.

• Hidden gem: The Abbey of SS. Flora e Lucilla (43.2628° N, 11.7329° E) is a Romanesque jewel surrounded by cypress groves, open 10–12 and 15–17.
• Wine note: Stop at Fattoria Santa Vittoria in Pozzo della Chiana for a free tour of their cellars.

Road quality on the SS73 is excellent, with modern guardrails and clear signage. However, wildlife (wild boar) crossings are common near wooded sections between Buonconvento and Lucignano—speed limits drop to 70 km/h there. Mobile phone reception is consistent except in the 2 km tunnel near Rigomagno. Emergency call boxes appear every 2 km.

For families, the Parco Avventura (adventure park) at Ciggiano (43.3450° N, 11.6900° E) offers tree-climbing courses for ages 4+. A child-friendly rest stop: the Piazzale di Lucignano's playground with picnic tables and shade. Nursing mothers can find baby-changing facilities at the Autogrill Valdichiana (SS73 km 52, both directions).

Pets are welcome at the Agriturismo La Bandita (Lucignano), which has a fenced dog park. Most restaurants in Arezzo's historic center allow well-behaved dogs on leashes. Carry water; public fountains are rare after Buonconvento. Fatigue management: designated rest areas exist at km 30 (San Giovanni d'Asso) and km 55 (Lucignano Ovest)—both have benches and vending machines.

• Safety tip: Use daytime running lights even in clear weather—many local drivers expect it.
• Emergency: Dial 112; closest hospital is Ospedale della Valdichiana in Montepulciano (30 min from route).
