Passo del Bernina, or Bernina Pass, is a high mountain pass in the Swiss Alps connecting the Engadin valley with the Italian-speaking Val Poschiavo. It's renowned for its stunning panoramic views, glaciers, and alpine landscapes. The pass is generally accessible by car and the Rhaetian Railway, a UNESCO World Heritage site. While solo visits are easily manageable, guided tours offer deeper insights into the region's geology and history. Seasonal restrictions apply, especially during winter (typically November to May), when the pass might be temporarily closed due to heavy snowfall; always check road conditions beforehand. Costs vary depending on transport and activities, but expect to pay for tolls if driving and fares for the train. A typical visit can range from a few hours to a full day, depending on whether you're just passing through or planning hikes and explorations.
