"Despite being so close to the harbor and the ocean, Reykjavík’s city lake has a charm and atmosphere all its own. Bordered by a main road on one side and a string of pretty, colorful residences on the other, the natural, stone-edged Tjörninis home to a community of ducks, swans, and geese that hang out here even in winter. A popular strolling spot to clear the cobwebs after a night out, it’s also often busy with local families and visitors, who comearmed with bread for the waterfowl(butbeware of the seagulls—theycan be aggressive). The nearby Reykjavík City Hall is also worth a look for its huge 3-D relief map of Iceland , featuring clearly marked glaciers, volcanoes, and fjords."
