Cantabria
Cantabria is an autonomous region on Spain's north coast. Santander, the capital, is a port on the Bay of Biscay, known for its long, curving El Sardinero Beach, and Cabo Mayor lighthouse. In the forested Cantabrian Mountains, Picos de Europa National Park has hiking trails and ski areas. The thousands of caves in Cantabria include El Soplao, with unusual stalactites and sheets of calcite hanging from the roof.
