Yes, you can take a day trip to the Dolomites from Venice in 2026, but it is an "intense" full-day commitment. The drive from Venice to the heart of the mountains (like Cortina d'Ampezzo) takes approximately 2 to 2.5 hours each way. If you use public transport, the journey involves multiple bus and train transfers, making it nearly impossible for a single day; therefore, private car tours or a rental car are the only realistic options. A well-planned day trip will allow you to see iconic spots like Lake Misurina, the Tre Cime di Lavaredo (Three Peaks), and the chic mountain town of Cortina. Peer-to-peer advice: don't try to "hike" the Dolomites on a day trip; instead, focus on the "scenic drive" and use cable cars to reach high-altitude viewpoints quickly. It is a spectacular contrast to the canals of Venice, but be prepared for a 12-hour day that involves at least 5 hours of total transit time.
