Discover Iceland's authentic hot spring experience at the Secret Lagoon, offering warm, natural waters, scenic views, and a peaceful atmosphere.

When considering a visit to Iceland’s famous geothermal pools, the Secret Lagoon in Flúðir emerges as a top choice for travelers seeking an authentic, less crowded alternative to the more commercialized blue lagoons. With an average rating of 4.7 out of 5 from over 1,400 reviews, this experience offers a genuine taste of Icelandic thermal bathing. For just $33 per person, you gain access to a natural hot spring pool that’s been serving visitors since 1891, along with modern facilities and stunning surroundings.
What we really love about the Secret Lagoon is how it combines history and nature—it’s not just about soaking in warm water, but about connecting with Iceland’s geothermal roots in a relaxed, friendly setting. One of the standout features is the steady flow of naturally heated water, which maintains a cozy 38-39°C (100-102°F). Plus, the chance to spot the Northern Lights in winter adds an extra dash of magic.
A potential consideration is that the facilities are more basic compared to larger, commercial lagoons—think simple changing rooms and limited amenities. This makes it perfect for travelers who appreciate authenticity over luxury. The lagoon suits those wanting a peaceful, local vibe, especially if you’re exploring the Golden Circle or nearby attractions.
This experience is ideal for adventurers, history buffs, or anyone seeking a serene retreat amid Iceland’s breathtaking landscape. It’s especially valuable if you want a budget-friendly hot spring without the crowds, but expect to do some planning around transportation, as it’s not included.

Most visitors find that arriving at Hvammsvegur in Flúðir is straightforward, but transportation isn’t included in the ticket price, so planning ahead is key. The lagoon’s remote location is part of its charm—you’re surrounded by lush Icelandic scenery, with mountains and moss-covered fields serving as a beautiful backdrop. Upon arrival, you’ll check in at the modest reception and be directed to the changing facilities, which are described as a good size, with plenty of lockers and a clean environment. A small note from reviews: there are only two toilets, so plan accordingly if you prefer complete privacy during changing.
The highlight of the experience is the natural hot spring pool, fed by geothermal springs bubbling up at a rate of 10 liters per second. The water stays fresh and clean thanks to this steady flow. Visitors often remark on the warmth—many say it’s perfect for relaxing, especially when the outside air is chilly, which is almost always the case in Iceland. One reviewer noted, “The water was so warm, very cool when it’s cold outside,” emphasizing how ideal it is in winter.
The new facilities, including showers and rest areas, are generally clean and well-maintained. Despite some reviews mentioning the lack of luxury, many appreciate the simplicity, feeling it adds to the authenticity. A couple of reviewers noted that towels are not included in the ticket price, costing an additional $7, so bringing your own towel is a smart move.
Once inside, you’ll find a peaceful, unhurried atmosphere. The lagoon is smaller than the Blue Lagoon, which means fewer travelers and a more relaxed vibe. Some visitors, like Emma, mentioned spending around 45 minutes to an hour enjoying the waters. The black pebble bottom and stone accents inside the lagoon give it a rustic charm that’s both visually appealing and tactilely soothing.
One of the unique features is the geyser-like eruption near the pool—an occasional burst of hot water that adds an element of natural spectacle. Reviewers also highly praise the friendly staff and the quality of the facilities, describing the environment as “very local” and “authentic,” which appeals to travelers seeking genuine Icelandic experiences.
The lagoon’s remote location means it’s often quieter than other attractions, especially during off-peak hours. Visiting in winter offers the added bonus of hopefully catching a Northern Lights display—a dreamy, glowing sky above the steaming waters. Even in summer, the peaceful setting provides a perfect escape from crowds.

The ticket offers a one-day validity, with specific starting times depending on availability—so it’s wise to check and reserve in advance. You can cancel up to 24 hours before your booked time for a full refund, giving flexibility if your plans change.
Remember, swimming attire is required, and showering without a swimsuit is mandatory before entering the pool—something many reviewers mentioned as a typical Icelandic custom. Unaccompanied minors are not allowed, keeping the environment safe and calm.
Since transportation isn’t included, most travelers either rent a car or join a guided tour that incorporates the lagoon. Its proximity to popular sights like Geysir and the Golden Circle makes it a great addition to a day trip, but being self-sufficient offers more flexibility.

Many reviewers expressed appreciation for the authentic Icelandic vibe. Unlike commercialized lagoons, the Secret Lagoon offers a more traditional experience that feels rooted in local life. Visitors love the steaming, warm water that provides respite after a day of sightseeing or exploring the nearby Golden Circle.
The price point of $33 is considered very reasonable, especially given the quality of the experience. While amenities are modest, the cleanliness, friendly staff, and stunning scenery make it a worthwhile visit. Some guests noted how the smaller size and less crowded environment heightened the sense of calm—something that larger, busier lagoons couldn’t match.
Travelers who prefer authentic, low-key experiences will find the Secret Lagoon irresistible. It’s especially suitable for those on a budget or wanting a less touristy alternative to bigger lagoons. Nature lovers, history enthusiasts, and anyone craving a peaceful soak amid Iceland’s natural beauty will appreciate the environment.

In a nutshell, the Secret Lagoon offers a genuine and affordable Icelandic hot spring experience in a setting that’s both scenic and historically significant. Its warm, bubbling waters and quieter vibe make it a wonderful respite after sightseeing or just a peaceful escape.
While facilities are functional rather than luxurious, many find that the authenticity and natural surroundings more than make up for this. The friendly staff, clean environment, and scenic location add to the overall appeal.
This experience is best suited for travellers seeking an authentic, relaxing, and budget-friendly soak. If you’re after a quiet, immersive geothermal bath that lets you connect with Iceland’s volcanic roots, the Secret Lagoon is a superb choice. For those who want a more commercialized spa or luxury amenities, it might feel a bit basic, but for pure, natural pleasure, it’s hard to beat.
