The journey begins in the flat, lush Po Valley, with rice paddies and canals. As you approach Belluno, the terrain rises into the Venetian Prealps. The A27 corridor offers dramatic views of the Nevegal peaks. After Tai di Cadore, the road snakes through the Cadore region, dotted with small villages like Pieve di Cadore (birthplace of Titian). The border crossing at Monte Croce di Comelico (Passo di Monte Croce) sits at 1,636 meters, marking the transition to the Austrian Gailtal.

• UNESCO site nearby: The Dolomites, a World Heritage Site, are visible from the route, especially around Auronzo di Cadore. A short detour to Lake Misurina (5 km) offers views of the Tre Cime di Lavaredo.
• Climatic conditions: Expect cool, crisp air above 1,500 m even in summer. Autumn brings golden larches; winter requires snow tires (mandatory in Austria Nov-Apr).
• Scenic sunset: Stop at the Monte Croce Pass lookout west of the border, where the setting sun paints the limestone peaks orange.

Local commerce: In Pieve di Cadore, buy authentic ladino crafts—hand-carved wooden masks or local honey.
