Blue Lagoon: Retreat Spa Experience & Private Changing Suite

The best part of this experience is the private Retreat Lagoon, where the same blue geothermal water found in Iceland’s famous Blue Lagoon feels calmer and less crowded. You get five hours to move between the water, lava-carved relaxation rooms, a sauna, steam cave, fireplace, viewing deck, and cold plunge.

I like the private changing suite, which gives you a spacious place to shower and dry off with robes, towels, flip-flops, and skincare products already waiting. I also like the Blue Lagoon Ritual, a self-guided treatment using salt, silica mud, algae, and face and body oil. The main drawback is the price: at $724 for two, this is a major splurge, and food and swimwear are extra.

Key points to know before you book

• The Retreat Lagoon is the quiet heart of the visit: It offers the Blue Lagoon’s geothermal water through a more private spa setting.
• Your five hours include much more than a soak: You can use the sauna, steam cave, fireplace area, relaxation spaces, viewing deck, cold plunge, and public Blue Lagoon.
• The private suite makes this especially suited to couples: Two people share a dedicated changing space with robes, towels, flip-flops, and Blue Lagoon skincare amenities.
• The Blue Lagoon Ritual is self-applied: You work through salt scrub, silica mud, algae mask, and nourishing oil at your own pace.
• The price buys privacy, not just entry: At $724 per couple, the value depends on how much you care about quiet space and a slower spa visit.
• Electronic devices stay outside: Cameras and other devices are not permitted, though staff can take a Retreat Lagoon photo and email it to you.

Why the Retreat Spa feels different from the main Blue Lagoon

The Blue Lagoon is famous for its broad geothermal pool and striking setting on the Reykjanes Peninsula. The Retreat Spa takes that idea in a quieter direction, placing you in a lava-rock complex with smaller, more private spaces and a dedicated entrance to the Retreat Lagoon.

I like the way the experience gives you room to set your own pace. There is no tight sequence of treatments to follow. After check-in, you receive a briefing, see your private changing suite, and then choose how to use the next five hours.

That freedom matters. You can start in the water, take a break in the sauna, sit by the fireplace, try the steam cave, or head to the viewing deck. The setting is designed for slow movement rather than a busy schedule.

The volcanic design is central to the mood. The concourse is carved from lava rock, and the relaxation spaces are arranged around the geothermal water. This is not a standard hotel spa with a pool added on. The rock, mineral water, steam, and heat all work together to create a distinctly Icelandic setting.

The quiet comes with a rule that some people will love and others may find inconvenient: no cameras or electronic devices are allowed in the spa. I see the logic. You are less likely to check messages or spend the afternoon taking photos. If you want a picture in the Retreat Lagoon, staff can take one for you and email it later.

Arriving at Blue Lagoon and reaching The Retreat

By car, Blue Lagoon is about 20 minutes from Keflavík Airport and about 50 minutes from Reykjavík. Follow the signs for The Retreat when you arrive. Day visitors to The Retreat have free parking.

If you arrive by bus, get off with the other passengers and walk to the Luggage House. An attendant can call the shuttle that takes you to The Retreat. This is a useful detail if you are carrying bags or arriving directly from the airport.

The spa can help store luggage, but you should still pack the essentials in an easy-to-reach place. Your key item is swimwear. It is not included, and you cannot use the pools without it.

The activity is private for your group, but that does not mean every part of the property is private. Your changing suite is private, while access to the Retreat Spa and the public Blue Lagoon is part of the wider facility. The Retreat Lagoon is the quieter water area connected to the spa.

Your private changing suite sets the tone

Check-in includes a briefing on the spa and suggestions for using the facilities. You are then shown to a private changing suite for up to two people.

The suite includes a large shower and dry area. Towels, bathrobes, flip-flops, and Blue Lagoon skincare amenities are supplied, so you do not need to pack those items.

This is one of the strongest reasons to consider the Retreat option instead of a basic Blue Lagoon visit. You have a private base for the day, with space to change, shower, dry off, and gather your things. For a couple marking a special occasion, that privacy may matter as much as the lagoon itself.

The suite also makes the five-hour duration easier to enjoy. You can leave the water without feeling that you must rush through a shared changing area. I would still bring only what you need, since the point of the visit is to spend less time managing belongings and more time using the spa.

The Retreat Lagoon is the main event

Start with the Retreat Lagoon. It contains the same blue geothermal water as the main Blue Lagoon, but the setting is more intimate and connected to the spa’s private areas.

You can soak, order your included drink, and look out across the mineral-rich waters and old lava. The drink is included, but food is not, so plan to eat separately if you expect to be there for the full five hours.

The lagoon is best understood as a place for lingering. You might spend part of the time sitting in the warm water, then move to a heated room or relaxation area before returning. The lack of cameras helps keep the atmosphere calm, though anyone who enjoys photographing every Icelandic stop will need to accept that the memories stay mostly in your head.

The spa also includes a viewing deck. It gives you a chance to step out of the water and take in the surroundings without ending the experience. Since the setting combines black volcanic rock with mineral-rich blue water, the deck adds visual interest to what could otherwise become a long indoor spa session.

Sauna, steam cave, fireplace, and cold plunge

The facilities are varied enough to keep the day from becoming one long soak. The sauna offers dry heat, while the steam cave provides a softer, more humid pause. These spaces let you change the physical rhythm of the visit.

There is also a fireplace and a nesting area for quiet rest. I like this mix because it gives you places to sit without ordering food or booking another treatment. You can simply pause, warm up, and return to the water when you feel ready.

The cold plunge well adds contrast. It will not appeal to everyone, but it gives you another way to use the spa beyond warm water and steam. The provided information does not specify its temperature or how long you should stay, so use it according to your own comfort.

A refreshment area is included as part of the spa, along with your drink of choice. If you want a proper meal, the Spa Restaurant serves seasonal, light dishes made with local ingredients. It has broad views of the water and centuries-old lava, and reservations are not required.

Food at the restaurant is an extra cost. That is worth noting when you judge the total price. The $724 package covers the spa experience and one drink, not a complete day of meals.

The Blue Lagoon Ritual uses four simple stages

The Blue Lagoon Ritual is the most structured part of the visit. It is self-applied, so you control the pace and amount of time spent on each step.

The treatment uses the lagoon’s main elements: salt, silica, algae, and minerals. The sequence includes:

• A salt scrub
• The well-known Silica Mud Mask
• An Algae Mask
• Blue Lagoon Skincare face and body oil

The salt scrub begins the treatment with a cleansing, polished feel. Next comes the silica mud mask, the product most closely associated with the Blue Lagoon. You apply it as directed, allow it to work, and rinse it away.

The algae mask follows. It is meant as a more nourishing stage, while the face and body oil finishes the treatment with moisture. Since this is not a private appointment with a therapist, you should book it for the ritual itself, not for hands-on massage or personal treatment advice.

That self-guided format can be a benefit. You do not have to keep to someone else’s timing, and you can make the process as relaxed as you want. It can also feel less luxurious if you expected a therapist-led service. The package description is clear that this is a self-applied experience.

Access to the public Blue Lagoon adds flexibility

Your Retreat Spa access includes entry to the main Blue Lagoon through a private entrance. This gives you two different bathing environments in one visit.

The Retreat Lagoon is the quieter option, with direct access to the spa’s relaxation rooms. The public Blue Lagoon offers the larger, more familiar setting associated with the property. You can compare both instead of choosing one and wondering what you missed.

I would use the Retreat Lagoon as the main base and treat the public area as an optional change of scene. If you prefer a more social or expansive pool setting, you may spend more time there. If peace and privacy are your priority, you may find the Retreat area enough on its own.

The private entrance is useful because you do not have to choose between an exclusive spa day and seeing the main attraction. Still, the public area is part of the value only if you actually want to use it. Someone seeking a secluded five-hour retreat may barely need it.

Is $724 for two a fair price?

At $724 per group of up to two, this is expensive by Iceland spa standards. The package is not a simple admission ticket. It combines five hours of access, a private changing suite, Retreat Lagoon entry, the public Blue Lagoon, spa facilities, skincare amenities, one drink, and the Blue Lagoon Ritual.

The strongest value comes from privacy and time. You are paying for a private room, a quieter lagoon, and the chance to settle into the spa without rushing. For two people who want a special occasion experience, the cost may feel reasonable once those details are important.

The value is weaker if you mainly want to try the famous lagoon for an hour or two. A shorter, less private visit would likely make more sense for a quick stop between the airport and Reykjavík. The Retreat package is built for people who intend to stay and use the facilities.

You should also budget for swimwear and food. The Spa Restaurant does not require a reservation, but lunch or a light meal increases the total cost. The package includes one drink, not unlimited refreshments.

Free cancellation is available up to 24 hours before the experience for a full refund. Starting times vary, so check availability before planning flights, buses, or a hotel transfer around the visit.

Who will enjoy this experience most?

I would recommend the Retreat Spa to couples who want quiet time and do not mind paying for comfort. The private changing suite, included robes and towels, and secluded lagoon make it especially well suited to a birthday, anniversary, honeymoon, or final Iceland treat.

It also suits people who prefer a flexible spa day to a fixed treatment schedule. You can move between water, heat, steam, rest, ritual, and food without being tied to a tour guide.

The minimum age is 12. Anyone under 18 must be with a parent or legal guardian, so this is not an adults-only experience in the strict sense. Children under 12 cannot use the spa.

The setting is wheelchair accessible, which makes the experience available to more visitors, though the provided details do not describe specific access arrangements for every facility. If you need luggage storage, staff at The Retreat can assist.

I would think twice if you want lively entertainment, lots of photos, or a therapist-led treatment. The no-device rule and self-applied ritual are part of the appeal, but they may not match your idea of a spa day.

Should you book the Blue Lagoon Retreat Spa?

Book it if you want to turn the Blue Lagoon into a slow, polished half-day experience for two. The private suite, quieter Retreat Lagoon, lava-carved spa rooms, included ritual, and public lagoon access give you plenty of ways to use the five hours.

Skip it if you mainly want a quick soak or if $724 would make the rest of your Iceland budget uncomfortable. The price is justified by privacy and time, not by a long list of guided activities.

For the right couple, this is a memorable way to rest near the end of an Iceland trip. Bring swimwear, leave your camera behind, and allow yourself to use the spa slowly. That is where the package earns its cost.
