3. How to Get There
By Air
- Zurich Airport (ZRH) – Switzerland’s largest international hub, about 150 km north of Airolo.
- Milan Malpensa (MXP) – A convenient option for travelers coming from Italy, roughly 200 km south.
From either airport, rent a car or hop on a train to reach Airolo.
By Train
The Gotthard Railway—one of Europe’s most famous rail lines—stops at Airolo station. Direct connections run from Zurich, Lucerne, and Milan, making the train a scenic and stress‑free way to approach the dam.

- From Milan: Follow the A2/E35 north, crossing the border into Switzerland and continuing to Airolo.
Parking is available near the lake’s shoreline, but spaces can fill quickly during peak summer weekends, so arriving early is advisable.
By Bus
Local bus routes (e.g., Autopostale line 1) link Airolo with nearby villages and the dam’s visitor area. Check the Ticino public transport website for up‑to‑date timetables.
