1 Best Sight in Puglia, Basilicata, and Calabria, Italy

The trulli in Alberobello itself are impressive, but the most scenic concentration of these unique conical structures is along a 15-km (9-mile) stretch of the SS172 (Alberobello–Martina Franca) through the tranquil Valle d'Itria. Stop to visit some of the area's vineyards and oil mills—many of which have a welcoming open-door policy—surrounded by vast groves of ancient gnarled olive trees.
