The Secret Lagoon

Natural hot pool close to Golden Circle

Secret Lagoon Iceland is situated within the Golden Circle area making it very easy to combine both attractions. What could be better than visiting three of Iceland’s most famous natural wonders followed by a relaxing bathe in a warm pool?

The Secret Lagoon

The Secret Lagoon is a beautiful thermal pool located in the small village of Flúðir in the heart of an area with high geothermal activity. The landscape around the pool is very natural, the steam rising from the water gives everything a surreal and mystical feel. The thermal pool is maintained at a constant temperature of 38/40 °C – lovely to experience at any time of year. Little pathways, geothermal hot spots and a small geyser, which erupts around every five minutes, are added attractions adjacent to the pool. There are lockers, comfortable changing rooms, and showers, a bar and eating areas. You cannot afford to miss this hidden gem!

The Oldest Pool in Iceland | Gamla Laugin Iceland

Secret Lagoon is known to most Icelanders as “Gamla Laugin” which means The Old Pool. But before the rise in tourism not so many people knew about it, and thus, this pool also became known as The Secret Lagoon.

The pool was created in the year 1891 and in 1909 the first swimming lessons were taught in the pool. You can only imagine how much the pool richened the life of Flúðir’s Inhabitants and opened up opportunities to enjoy a good soak. In 1947 a new swimming pool was opened in the town of Flúðir and after the pool was mostly forgotten until now.

Where is the Secret lagoon located

The Secret Lagoon is at Flúðir in South Iceland 97.5 km from Reykjavík, 164 km and 47 km from Selfoss. You need to take Highway 1 (the Ring Road) to the south and then road number 30.

The Secret Lagoon vs. the Blue Lagoon

Floating at the Blue Lagoon

The Secret lagoon is located in one of the most active geothermal areas in Iceland just like the Blue Lagoon but the difference is in the surroundings.  The Secret Lagoon is located in a fertile green valley but the Blue Lagoon located in the middle of a harsh lava field.

The Blue Lagoon has a unique turquoise blue color, for what it is known for, this is caused by algae and silica, the same as found in the blue waters of Mývatn Nature Baths. The Secret lagoon has more regular clear water. The water in both places is around 40°c (104 Fahrenheit).

Both places can be visited on a day tour out from the capital, Reykjavík and are unique in their own way. Visiting these places is nothing quite like visiting a regular swimming pool in Iceland and for that reason, the cost is higher. The Blue Lagoon does cost twice as much as the Secret Lagoon (their starting price) but their changing facilities, saunas, restaurants and steam rooms are also of another sort.

The warm water in the Blue Lagoon is believed to have healing powers for psoriasis and acne.

The size of the Blue lagoon compared to the Secret Lagoon is enormous.  The Blue Lagoon has two hotels, saunas, a steam bath and a few different geothermal pools. They have a cafeteria and a fancy restaurant, a gift shop with their own skin line.  The Secret lagoon has one pool and a cafeteria.

The history of the Secret Lagoon goes back to 1891 the Blue Lagoon was founded in 1992 when the lagoon was moved away from the Geothermal Energy plant.


It is quite hard to compare these two, they truly are nothing alike. The Blue Lagoon is more of a spa and has the facilities for you to stay a whole day or two, there you can get treatments and fancy meals and they even have luxury hotels. The Secret Lagoon is a charming small pool, a lot more low key and local. The experience as a whole is not longer than 1-3 hours but is a fantastic extra stop to make on the Golden Circle or with other activities in South Iceland.

The difference is so great a visit to both is advised!
