Nature has its tricks and Sørvágsvatn is one of its best. This is an optical illusion in the Faroe Islands, an autonomous administrative division of the Kingdom of Denmark. Also called Leitisvatn, this lake on the island of Vágar appears to float far above the ocean. In reality, it sits less than 30 metres above sea level. As the largest lake in the Faroes, Sørvágsvatn has a surface area of about 3.4 square kilometres and feeds the Bøsdalafossur waterfall, where its waters pour dramatically into the sea.

Sørvágsvatn reminds us why lakes are so vital. They not only provide recreation but also store freshwater, regulate local climates and support biodiversity. Yet today, many are under threat. Pollution, overuse, climate change and fluctuating water levels are placing increasing pressure on these fragile ecosystems. So, the next time you look at a map, think of lakes not just as dots of blue but as living, breathing parts of our world that deserve our care and attention.
