One of Iceland's most alluring features for me has always been its geothermal lagoons. These unique and magical spots, that aren't available in Ireland or England, provide a fantastic experience for the many visitors to Iceland.
TL;DR
I compare four of the most popular lagoons, that I have visited over the years: the Blue Lagoon, Sky Lagoon, Secret Lagoon, and Laugarvatn Fontana. Each destination has its own distinct charm and array of offerings, making it important to know what to expect. Spoiler - I finish though with a bit of a surprise.
Blue Lagoon: The Iconic Experience
The Blue Lagoon is arguably the most famous geothermal spa in Iceland, apparently attracting over 1.2 million visitors annually. Nestled in a lava field near Grindavík, its vibrant azure waters which are a run off from a thermo power station are rich in minerals, which are believed to have healing properties for the skin.
This lagoon offers luxurious amenities, including a range of spa treatments, a gourmet restaurant, and a bar serving local delicacies. For instance, visitors can pamper themselves with massages or rejuvenating facials while enjoying the warm, mineral-enriched waters. The lagoon's striking setting, framed by black lava rocks and lush moss, creates a striking atmosphere that is hard to match.
Its proximity to the airport, means that the Blue Lagoon can get quite busy, especially during peak tourist seasons. It is wise to make reservations in advance.
The entrance fee is higher than that of other lagoons - varying considerably depending on the overall experience.
Sky Lagoon: A New Contender
Sky Lagoon, a fresh addition to Iceland's geothermal spa offerings, is conveniently located just a short drive from Reykjavik. This lagoon features a stunning infinity edge that creates a seamless view of the Atlantic Ocean. We visited in the dark - so missed that.
One of Sky Lagoon's standout highlights is its unique seven-step wellness ritual. This experience includes a variety of wellness treatments like steam rooms, a refreshing cold plunge, and tranquil relaxation areas. The lagoon’s design emphasizes harmony with nature, featuring natural wood elements and panoramic views, though it's clearly man made.
Despite being newer, Sky Lagoon offers a more personalised experience than the Blue Lagoon and tends to be less crowded.
The entrance fee is a little lower, making it a more affordable option for travellers seeking relaxation without overspending.
Secret Lagoon: A Hidden Gem
For those longing for a true Icelandic experience, the Secret Lagoon is an absolute must-see. Situated in the small village of Flúðir, this lagoon is recognised as one of the oldest geothermal spas in the country, showcasing a more rustic vibe.
The Secret Lagoon features natural hot springs where steam rises dramatically from the water. Unlike more commercialised lagoons, it boasts more of a sense of tradition and connection to nature.
The entrance fee here is much more affordable,, making it an excellent choice for budget-conscious travelers. However, keep in mind the facilities are more basic compared to the Blue Lagoon and Sky Lagoon, so be ready for a more relaxed and laid-back atmosphere.
Laugarvatn Fontana: A Family-Friendly Option
If you're traveling with the family, Laugarvatn Fontana is a fantastic geothermal spa that promotes a friendly atmosphere. Conveniently located along Iceland's Golden Circle, this lagoon features several hot pools, steam rooms, and a sauna, all with beautiful views of Lake Laugarvatn.
Visitors can enjoy freshly baked bread cooked using geothermal heat, adding a unique touch to their experience. The lagoon is generally less crowded than the Blue Lagoon, making it suitable for families or anyone looking to relax without the hustle and bustle.
Entrance fees are much more reasonable, and the well-maintained facilities make it a solid option for families or those searching for a casual experience.
Making the Right Choice for You
Selecting the best lagoon in Iceland ultimately depends on your personal preferences and the experience you want.
If luxury and an iconic ambiance are your priorities, the Blue Lagoon remains unmatched, even though it can be crowded and pricey.
For an intimate setting with breathtaking views and wellness experiences, Sky Lagoon is an excellent choice.
If authenticity and affordability are essential, the Secret Lagoon serves as a hidden gem that delivers a genuine taste of Icelandic culture.
Lastly, Laugarvatn Fontana is perfect for family trips or those wishing for a laid-back atmosphere with cultural elements.
Each lagoon offers something unique, ensuring that there is an ideal spot for everyone. Whether you seek luxury, tranquility, authenticity, or family-friendly fun, Iceland's lagoons promise an unforgettable experience.
You'll enjoy the rejuvenating waters of this stunning island at each.
If you are adventurous, whilst not a lagoon, but a similar experience - I think my favourite is Reykjadalur Hot Spring Thermal River.
