Jokilsarlon Lagoon, Iceland © Molechaser
Jökulsárlón - literally, 'glacier lagoon' - is the largest glacial lake in Iceland, and an enormously popular tourist attraction. The site shot to prominence after being featured in Hollywood movies (most memorably, Batman Begins), and now attracts thousands of visitors each year. Caused by the retreat of the glacier known as Breiðamerkurjökull, the lagoon is now nearly a mile (1.5km) from the ocean's edge, and is over 814 feet (248m) deep. Most easily approached from the fishing town of Höfn on Iceland's southern coast, visitors in search of an indelible memory of their time in the country should definitely make the trip to Jökulsárlón, where luminous blue icebergs float eerily across the freezing water. Whatever you do, don't forget to pack a camera - Jökulsárlón is undoubtedly one of the best sights Iceland has to offer, and in such a staggeringly beautiful country, that's really saying something.
