Hurtigruten is sometimes referred to as the Norwegian Coastal Express. The 11 coastal ships sail almost the entire length of the country, completing the round-trip journey from Bergen to Kirkenes and back again in 12 days, calling 34 ports. The trip along the Norwegian coast has been described as the "World's Most Beautiful Sea Voyage." Hurtigruten's explorer ships MS Fram, MS Midnatsol and MS Nordstjernen offer Explorer voyages to Antarctica, Greenland, Iceland, Spitsbergen, North and South America, and Europe. In addition MS Midnatsol crosses the Atlantic Ocean twice every year.
