Nestled amidst Iceland’s rugged lava fields, the Blue Lagoon is one of the world’s most famous geothermal spas. Whether you’re visiting for the iconic milky-blue waters, luxurious spa treatments, or a serene retreat, our Blue Lagoon ultimate guide will cover everything you need to know, from essential tips to unique experiences, so you can make the most of your visit.
Note: Given the Blue Lagoon's location in a geothermally active region, volcanic events, while notable, are part of the natural dynamics of the area. The Blue Lagoon team continuously monitors geological activity to ensure visitor safety and promptly communicates any operational changes. For the latest updates and information, we encourage visitors to check the official Blue Lagoon website or contact their customer service directly.
What Is the Blue Lagoon?
The Blue Lagoon is a geothermal spa located in Iceland's Reykjanes Peninsula. The warm, mineral-rich waters are naturally heated by nearby geothermal activity and are believed to have healing properties for the skin. The lagoon gets its stunning blue hue from the silica content in the water, which reflects sunlight.
The Blue Lagoon’s restorative properties stem from its unique geothermal seawater, a blend of freshwater and saltwater sourced from deep beneath the Earth’s surface. Rich in silica, algae, and minerals, the water is naturally heated and enriched by Iceland’s volcanic environment. Silica strengthens the skin’s barrier, locking in moisture and leaving it smoother, while algae boost collagen production and fight signs of aging with powerful antioxidants. Minerals like magnesium and potassium improve circulation, reduce inflammation, and rejuvenate skin cells.
Scientific studies have shown the lagoon’s benefits for conditions like psoriasis, as the water soothes irritation and promotes skin healing (they even have a medical clinic). The warm water, maintained at 37–40°C (98–104°F), also provides muscle relaxation and stress relief by enhancing circulation and lowering cortisol levels. Visitors often report softer, healthier skin and a profound sense of relaxation after their soak. Whether you’re seeking therapeutic benefits or simply a moment of tranquility, the Blue Lagoon offers a scientifically-supported, naturally rejuvenating experience.

How to Get to the Blue Lagoon
The Blue Lagoon is quite accessible from the Keflavik International Airport. Any hotel in Reykjavik will either have shuttles or be able to recommend transportation options. We like to bookend our trip by either going straight there upon landing, or making a day or so of it on our way out. Because of the all-encompassing facilities with storage, you can bring your luggage with ease. Here are some transportation options:
By Car: The lagoon is approximately a 45-minute drive from Reykjavik and 20 minutes from Keflavik Airport. Iceland’s roads are well-maintained and easy to navigate, and the Blue Lagoon is clearly marked on major routes. Please refer to our Iceland transportation guide on car rentals.
Shuttle / Bus Services: Many companies offer round-trip shuttle services from Reykjavik, Keflavik Airport, or even your hotel. These are great options if you’re not renting a car. We've used FlyBus and the country run public transportation Strætó and have had wonderful experiences on both.
Taxi:Â Taxis are readily available but can be expensive compared to shuttle services or self-driving. One of the most popular services is Hreyfill. Download the app and call a taxi with ease. Hopp has recently expanded from scooter services to include taxis as well.
Parking: Free parking is available on-site for all visitors. The parking lot is spacious and located a short walk from the main entrance, making it convenient for guests arriving by car. Additionally, there are designated spots for electric vehicles equipped with charging stations.
Whether you drive yourself or take advantage of shuttle services, getting to the Blue Lagoon is pretty straightforward and relatively stress-free. Planning your transportation in advance will help you enjoy a seamless experience (and likely cost less).

What to Expect During Your Visit
We've compiled a list of things to anticipate and / or bring to ensure your visit is free of any complications:
Things to Bring: Most of this can be bought or rented while there, but it's still nice to have your own things (at a fraction of the cost).
Swimwear / Towel: Swim attire is mandatory for entering the lagoon, but rentals are available.
Waterproof Phone Case: Essential if you want to take photos in the lagoon without risking damage to your device.
Flip-Flops or Water Shoes: While the lagoon's bottom is soft, the surrounding paths can be slippery. There are hooks to hang robes and cubbies to leave shoes.
Hair Ties: People with long hair, do not forget hair ties! Do not get your hair in the water, it will be one of the worst travel decisions of your life. Lol.
Conditioner: This is provided, however if you have conditioner you prefer, it's best to bring a travel size version of it. The high silica content can make hair dry and brittle, so apply a generous amount of conditioner BEFORE entering the water (see below).
Reusable Water Bottle: Staying hydrated is important, as the warm waters can cause dehydration. There are in-water bars that offer water as well. This is more for pre- and post-visit.
Sunscreen and Sunglasses: It gets sunny! Depending on the time of day / year, it's wise to bring skin and eye protection.
What to Do in the Lagoon
Silica Face Masks: In-water stations throughout the lagoon offer complimentary silica mud masks (and more options depending on your admission price). Apply for a rejuvenating skin treatment.
The Blue Lagoon Ritual: At The Retreat, guests can enjoy a three-step treatment using silica, algae, and minerals for full-body rejuvenation.
Relaxation Spots: Look for quieter corners of the lagoon or rest on the in-water benches /seats.
In-Water Bar: Take advantage of the moment with a morning or afternoon beer or cocktail.
Dining at the Blue Lagoon
Lava Restaurant: Perfect for casual dining with stunning views of the lagoon. The menu features Icelandic specialties with a modern twist.
Moss Restaurant: For an upscale experience, this Michelin-starred restaurant offers tasting menus with locally sourced ingredients and expertly paired wines.
Blue Café: Grab a quick snack or drink between spa sessions.
Spa Restaurant: Gourmet delicacies at the Retreat Spa (see above)
Hair and Skin Care Tips
Hair Protection: Silica can make your hair feel a bit stiff and clumpy and difficult to manage if it gets wet. Even though silica itself isn't inherently harmful to hair, to prevent this annoyance, apply conditioner before entering the lagoon and avoid wetting your hair entirely if possible.
Post-Visit Shower / Hydration: Thoroughly rinse your hair and skin after your soak to remove any lingering silica residue. Apply lotion or oil liberally afterward to lock in moisture. You will feel amazing.
Practical Tips
Book in Advance:Â Tickets do sell out quickly, especially during high seasonal times. So reserve online as early as possible.
Timing:Â Visit during off-peak hours (early morning or late evening) for a more tranquil (and sometimes cheapert) experience.
Locker Use:Â Lockers are provided for all guests to store belongings safely. These are great, and while you may feel like you're at the gym, you can come and go, open and close with ease.
Pack Essentials: Don’t forget your gear - swimwear, towels, and reusable water bottles. Some spas provide rentals, but bringing your own is cost-effective.
