A mere 25 km (15.5 miles) separate the glaciers of the Bernina Range and the pass at 2328 meters (7,637 ft) from the orchards and palm trees at the valley’s mouth in Campocologno  at 553 meters (1749 ft). On either side the valley is hemmed in by 3000-meter (almost 10,000-ft) high peaks, the highest of which, the Piz Palü, reaches 3900 meters (12,800 ft). All climate and vegetation zones are represented here, from extreme nival to Mediterranean, which provide a broad range of agricultural products.
