Sweden
Sweden's only coral reef hides beneath the surface of its westernmost archipelago.
The Koster Islands sit at Sweden's westernmost edge, two car-free granite outcrops ringed by the country's only marine national park. Beneath the surface, cold-water coral and kelp forests hold life that belongs to the Atlantic rather than the Baltic. Above it, the islands run on bicycles and ferry timetables.
Kosterhavet became Sweden's first marine national park in 2009, protecting some 390 square kilometres of unusually salty, unusually deep sea. Its headline resident is Lophelia pertusa — Sweden's only cold-water coral reef — anchoring a cast of thousands of marine species, the richest waters in the country. Grey seals breed and haul out across the outer skerries; marked snorkel shallows trace the reef edges; and the Koster islands themselves are all bicycle paths, meadows and fishing hamlets, served by ferry from Strömstad with no private cars at all. It is Sweden doing the Atlantic in miniature — and doing it slowly, which is the point.
