Located a short drive from Keflavik airport and 50 mins away from Reykjavik, the Blue Lagoon is one of the most popular destinations in any trip to Iceland. This natural wonder features geothermal seawater. In a country where the weather is usually freezing cold, enjoying these warm healing waters translates into pure happiness. In addition to the lagoon itself, the facilities include two hotels, various restaurants, a retreat spa and a shop to take home your favorite skincare products.
