In 2026, renting a car in Tuscany is considered highly worth it if your goal is to explore the "Val d'Orcia" countryside, visit hilltop villages like Montepulciano, or reach remote wineries. While the train system efficiently connects Florence, Pisa, and Siena, it does not reach the iconic rolling hills and cypress-lined roads that define the region. A car offers the freedom to stop at "wait, pull over!" viewpoints that bus schedules don't allow. However, if your itinerary is strictly limited to major city centers, a car becomes a liability due to ZTL (Limited Traffic Zones), where driving a non-authorized vehicle can result in fines exceeding 100 EUR. The best strategy in 2026 is a "hybrid" trip: use trains for the cities and rent a small car for 3–4 days to get lost in the countryside, where a compact vehicle is better for narrow medieval lanes and limited parking.
