Fodor's Expert Review Viamala Gorge
This narrow but dramatic gorge was carved thousands of years ago by glacial ice. Shortly after the start of the gorge, climb down 359 steps to view the river, rock formations, and a mid-18th-century bridge. You can reach the gorge by heading south from Chun toward the San Bernardino pass on the A13, then turn off at Thusis and follow the sign for the Viamala. This "bad road" was used by Romans and traders over centuries. It runs about 6 km (3½ miles) alongside the gorge.
