If you're looking up lagoons in Iceland, we're pretty sure the Secret Lagoon doesn't come up very often. That's because when the Blue Lagoon was opened, people completely forgot about this gem - and now it's exclusivity is one of the best parts about it! The Secret Lagoon, Iceland's first swimming pool is a 90-minute drive from Reykjavik, and is definitely the place to go if you're looking for a relaxing afternoon, surrounded by nature. The geothermal pool is at comfortable temperatures of 36-40°C (97-104°F) - a great way to keep warm especially on a chilly day. If you visit during the winter, you'll even get a chance to see the Northern Lights while relaxing in the bath. With convenient transfers from your hotel in the city to the Secret Lagoon, all you have to do is kick back, relax, and take a wonderful dip in the geothermal pool. Just make sure you don't forget your swimsuits!
