Lago d'Orta is one of the most beautiful and least crowded lakes in northern Italy, easily rivalling the more famous Lago Maggiore next door. The tiny Isola San Giulio, reached by boat from the waterfront, is a medieval gem of cobbled lanes you can walk around in half an hour, with a Romanesque basilica at its centre and a working Benedictine monastery on its eastern half.
The town of Orta San Giulio itself is a delight, with a handsome piazza on the water, good restaurants along the lakefront, and regular boat services to the island. Above town, the wooded paths of the Sacro Monte — a UNESCO-listed Counter-Reformation pilgrimage route with twenty chapels of life-sized polychrome figures — make the best long walk in the area. At the entrance to town, the Moorish-revival Villa Crespi is the most unlikely building on any Italian lake.
Orta makes a fine day trip from Stresa or a peaceful base for exploring the quieter side of the Italian lake district.
