The Westman Islands, a short ferry hop off Iceland's south coast, host the largest puffin colony on Earth — around a million pairs from May to August. Walk the cliff paths at Stórhöfði for close-range views of the world's most cartoonish seabird. Time a visit for late August and children can join the local 'puffin patrol', rescuing disoriented fledglings from the town streets at night and releasing them to sea next morning. Unbeatable.
