Blue Lagoon

It’s easy to visit: either come by bus (the Flybus to the airport stops here) or by car. The lagoon is 40 minutes from Reykjavik and 20 minutes from the airport and is well-signposted (look out for Blaa Lonid).

Unsurprisingly, the pool is enormously popular, so bookings are essential whatever time of year you visit. You can purchase VIP tickets which allow you to access a private area of the pool, as well as a lounge and viewing platform.

The luxurious Blue Lagoon Retreat hotel, on the pool’s western shore, has access to its own private section.

Do be aware that the mineralised water can discolour metals, including silver – so be sure to remove jewellery before you bathe.

It’s open all year round, seven days a week. Winter sees far fewer visitors, and booking a visit for early morning or late evening usually provides a more restful experience.

Try it beneath the midnight sun in June, July or August, in the snow in winter or during the Iceland Airwaves festival in October when bands play around the edges. Under dark winter skies, you might even be lucky enough to spy the Northern Lights while you bathe: November to February is the main aurora season.
