Iceland’s rugged coastline, of more than 3,000 miles (4,800 km), meets the Greenland Sea on the north, the Norwegian Sea on the east, the Atlantic Ocean on the south and west, and the Denmark Strait—which separates it from Greenland on the northwest. Most Icelandic beaches are black because of the volcanic nature of their surroundings as there is old lava almost everywhere by the Icelandic shores. There are also charismatic mountain peaks, spectacular waves, icebergs melting on the black sand, beautiful basalt sea stacks, small fishing villages, and high coastal cliffs hosting bustling seabird colonies.
