Iceland is so overflowing with wonders both natural and man-made, you wouldn’t think it would need another, but, in 2021, along came the Sky Lagoon. Just on the southern outskirts of the capital Reykjavík, it’s a natural geothermal pool and spa that seems to merge with the ocean. Bathers emerge from the cliffs into the lagoon’s steaming waters, with wide open views of the Atlantic out front, and spa rooms squirrelled away in traditional turf houses to the sides. The experience is magical — especially if you manage to time your swim with sunset or a display of the Northern Lights. skylagoon.com visitreykjavik.is
