Experience Iceland's first natural hot spring lagoon, the Secret Lagoon, with warm waters, pristine facilities, and the chance to see the Northern Lights—only $33.


The Secret Lagoon is known locally as Gamla Laugin, which translates to “Old Pool.” Built in 1891, it holds the distinction of being Iceland’s first swimming pool. This historic site has maintained its authentic charm while receiving recent upgrades, making it a perfect place for visitors to experience a piece of Icelandic history. The lagoon’s natural hot spring waters flow steadily, feeding the pool with 38-39°C water that bubbles up from deep beneath the earth at 10 liters per second, ensuring a fresh, warm experience each time.
The natural environment surrounding Gamla Laugin emphasizes a rustic, untouched feel, with the pool’s black pebble bottom adding to its authentic vibe. Visitors often appreciate that the facility’s facilities—including changing rooms, showers, lockers, and rest areas—are clean and well-maintained, reflecting a genuine Icelandic approach to simplicity and functionality. The historic charm combined with the recent renovations makes this lagoon a less crowded and more relaxed alternative to the more commercial options such as the Blue Lagoon.

The Secret Lagoon is situated in Flúðir, a peaceful area in the Southern Region of Iceland. Its remote position makes it a great stop during a Golden Circle tour or a scenic drive along the south coast. It is approximately one hour from Geysir, 1 hour and 20 minutes from Reykjavik, and two hours from Vik. This accessibility means visitors can easily fit the lagoon into a day of sightseeing, pairing it with nearby natural wonders. Its secluded setting offers a more tranquil environment compared to larger, busier hot springs.
Because of its location, the lagoon is ideal for travelers exploring the Icelandic countryside who want a relaxing break without sacrificing the opportunity to enjoy Iceland’s geothermal riches. Whether visiting in winter or summer, the scenery offers a peaceful backdrop while soaking in the warm waters.

The latest upgrades at the Secret Lagoon include modern changing rooms, showers, lockers, and resting areas. Guests are expected to shower without a swimsuit before entering the pool—a standard practice in Icelandic hot springs—and unaccompanied minors are not allowed. The shower area requires swimsuit use, and nudity in bathrooms is common and part of the local customs.
The pool itself is the main attraction, with warm water maintained at a comfortable temperature, especially appealing during colder months. The facility also features a bar and restaurant where visitors can purchase drinks and snacks, with cold prepacked food available. While the facilities are generally praised for cleanliness and efficient organization, some reviews mention that towels are not included in the ticket price and cost around $7 to rent, so bringing your own can enhance convenience.
The main draw of this tour is the hot spring water fed directly from the earth, creating a relaxing thermal environment.

The steady flow of 10 liters per second ensures the pool remains constantly replenished, maintaining water quality and temperature.
This setup offers a genuine Icelandic feel, connecting visitors with the natural geothermal activity that makes Iceland famous. The black pebble bottom and natural surroundings contribute further to the authentic experience, making it a perfect spot to unwind after sightseeing or simply enjoy a peaceful moment in nature.
