Blue Lagoon: Retreat Spa Experience & Private Changing Suite

Volcanic rock hides a very calm place. The Blue Lagoon Retreat Spa gives you five hours in a quiet underground spa with a private changing suite, the secluded Retreat Lagoon, and direct access to the main Blue Lagoon. I like the feeling of privacy here, especially for couples, and I like that the Blue Lagoon Ritual gives your visit a clear purpose beyond simply sitting in warm water. The main drawback is the price: $724 for two is a serious splurge, and food, swimwear, and transportation are not included.

You get much more than a premium changing room. Your booking includes sauna and steam-cave access, relaxation areas, a cold plunge well, a drink, skincare products, and the self-applied ritual using silica, algae, salt, and oil. The spa also limits modern distractions by banning cameras and electronic devices, which may feel refreshing or inconvenient depending on how much you want photographs.

Key points at a glance

• A private lagoon without the main pool crowds: The Retreat Lagoon uses the same blue geothermal water as the Blue Lagoon, but offers a quieter setting for up to two people.
• Your own changing suite: A large shower, dry area, towels, robes, flip-flops, and Blue Lagoon Skincare products are provided.
• A full five-hour visit: You have time to enjoy the spa slowly instead of rushing from one treatment to the next.
• The Blue Lagoon Ritual is self-applied: You work through salt, silica, algae, and nourishing oil treatments at your own pace.
• Subterranean volcanic design: Lava rock, a steam cave, fireplace, nesting area, and viewing deck give the spa a strong sense of place.
• Easy airport access: The Blue Lagoon is about 20 minutes from Keflavík Airport and 50 minutes from Reykjavík by car.

Why the Retreat Spa feels different

The main Blue Lagoon is famous, but fame brings crowds. The Retreat Spa is designed as a quieter counterpart, built into the volcanic earth on the Reykjanes Peninsula. You enter through a concourse of lava rock, then move through a series of warm, dim, cocoon-like spaces.

I like that the architecture is not just decoration. The rough stone, mineral-rich water, fireplace, and steam cave all reinforce the setting. You are not in a generic hotel spa with a few Icelandic touches added later. The volcanic ground is part of the experience.

The spa is also built around pauses. You can sit near the fireplace, relax in a nesting area, step into the sauna, or use the viewing deck. The cold plunge well offers a sharp contrast to the warm water and steam. You do not need to treat the five hours as a strict schedule. In fact, the visit works best when you leave room for doing very little.

That slower pace is part of the value, but it also explains why this experience will not suit everyone. If your ideal Iceland stop involves hiking, sightseeing, or constant activity, five hours in a spa may feel excessive. If you have been driving, flying, or touring for several days, it may feel exactly right.

Check-in, briefing, and the private changing suite

Your visit begins with check-in and a briefing about the spa. Staff then lead you to a private changing suite for two. The private room matters because it removes one of the ordinary annoyances of a public spa: changing in a busy communal space and trying to keep track of your belongings.

The suite includes a large shower and a dry area. Towels, bathrobes, flip-flops, and Blue Lagoon Skincare amenities are supplied, so you do not need to pack a full spa kit. You do need to bring swimwear. Swimwear is not included.

If you are carrying luggage, staff can assist with storage. This makes the Retreat Spa practical as a stop between Keflavík Airport and Reykjavík, though you should still allow time to get settled rather than arriving at the last minute.

The spa is wheelchair accessible. The minimum age is 12, and anyone under 18 must be with a parent or legal guardian. Children under 12 cannot use the spa, so this is best treated as an adult-oriented break.

The Retreat Lagoon, a quieter place to soak

I would begin with the Retreat Lagoon. It uses the same blue geothermal water as the main Blue Lagoon, but the setting is more intimate and less exposed to the general pool crowd. You can settle into the warm water, order a drink, and let the visit start without rushing.

The private lagoon is the heart of this package. The public Blue Lagoon is the better choice if your priority is simply access to the famous pool at the lowest available cost. The Retreat Lagoon is for people who care about space, quiet, and a more polished visit.

The included drink is a small detail, but it helps the time feel complete. You can enjoy it while looking across the water and the surrounding lava. Food is not included, though, so do not confuse the drink with a meal.

Staff can take a photo for you in the Retreat Lagoon and email it to you. This is useful because cameras and electronic devices are not allowed inside the spa. You will not be able to carry your phone from room to room for casual pictures, and the rule is part of the spa’s effort to keep the setting quiet.

For some people, the no-phone rule will be a major benefit. For others, it may be frustrating, especially in a place as visually striking as this. Plan to enjoy the memory rather than document every minute.

The Blue Lagoon Ritual, step by step

The Blue Lagoon Ritual is the most hands-on part of the visit. It is not a therapist-led massage or a private facial. You apply the treatments yourself in a cycle based on three natural elements associated with the lagoon: silica, algae, and minerals.

The ritual includes:

• A salt scrub
• The Silica Mud Mask
• The Algae Mask
• Nourishing face and body oil from Blue Lagoon Skincare

The salt scrub gives you an active start. It is designed to smooth the skin, and it makes the ritual feel more involved than simply applying one mask and waiting. Use a gentle touch, especially if your skin is sensitive.

Next comes the Silica Mud Mask, the best-known treatment in the Blue Lagoon routine. It has a mineral feel and is meant to be part of the lagoon’s skin-care tradition. You apply it yourself, so you control how much you use and how long you spend with it.

The Algae Mask follows. It adds a second treatment with a different texture and purpose. The sequence works well because it gives the soak a rhythm: scrub, mask, rinse, then continue relaxing.

The final step is face and body oil. This is the comforting finish after the salt and masks. It leaves the ritual feeling like a complete spa routine rather than a collection of products.

I like the freedom of a self-applied treatment. You do not have to match a therapist’s timing, and couples can move through the process together. The tradeoff is that anyone hoping for personal treatment from a spa professional may find the ritual less special than expected.

Sauna, steam cave, fireplace, and viewing deck

The Retreat Spa gives you several places to break up the lagoon time. The sauna provides dry heat, while the steam cave offers a wetter, more enclosed setting. The volcanic surroundings make the steam cave feel more connected to the site than a standard tiled steam room.

The fireplace and nesting area are made for a quiet reset. After the warm water or ritual, you can dry off, wrap yourself in the robe, and sit without needing to do anything. That sounds simple, but it is often what turns a busy sightseeing day into a proper rest day.

The viewing deck offers a change of scene. You can look across the mineral-rich waters and old lava around the spa. It is not a sightseeing platform in the usual sense, but it gives you a chance to see the setting from above instead of experiencing it only from the water.

The cold plunge well provides the strongest physical contrast. Moving from hot water or steam into cold water is not for everyone, and no one should feel pressured to use it. It is there for those who enjoy a brisk change in temperature as part of a sauna routine.

The variety matters because five hours is too long to spend in one pool without a break. You can rotate between water, heat, rest, and fresh air. That makes the visit feel spacious rather than repetitive.

Eating at the Spa Restaurant

The Spa Restaurant serves a seasonal menu of light meals made with fresh local ingredients. It has wide views of the mineral-rich water and centuries-old lava, so the setting is a natural part of the meal.

Food is not included in the $724 package. You pay separately, but you do not need a reservation. That gives you flexibility if you decide to eat before the spa, during your visit, or afterward.

I would treat the restaurant as a useful addition rather than a reason to book the Retreat Spa. The package is priced around privacy and spa access, not dining. Still, having a restaurant on site makes the five-hour stay easier, especially if you do not want to leave the property for lunch.

The menu is described as light and nourishing, which fits the mood of the spa. If you want a long, formal meal with a large selection, you should check the available menu when you arrive. The information provided does not promise a particular dish or meal size.

Is $724 for two a good value?

At $724 per group of up to two, this is one of Iceland’s luxury splurges. The price works out to $362 per person if two people share it, before food and any travel costs.

You are paying for several things at once:

• Five hours of access
• A private changing suite
• The Retreat Lagoon
• The main Blue Lagoon public area
• Sauna, steam cave, relaxation rooms, and viewing deck
• The Blue Lagoon Ritual
• A drink
• Towels, robes, flip-flops, and skincare amenities

The private suite and quiet lagoon are the biggest value points. If you only want to try the famous geothermal water, a less expensive Blue Lagoon option may make more sense. If you want privacy, a slower pace, and a polished couple’s experience, the Retreat Spa justifies more of its cost.

The five-hour duration also matters. You are not paying for a quick dip. You have enough time to use the facilities, complete the ritual, rest, eat separately at the Spa Restaurant, and still return to the water. The package becomes poor value only if you plan to stay for a short time or dislike spa-style relaxation.

I would also compare the cost with your wider Iceland plans. This is a good choice for a special occasion, a recovery day after touring, or a final stop before flying home. It is less convincing if your budget is tight and you still need to pay for several major Iceland activities.

Getting there from Keflavík or Reykjavík

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

The airport location makes the spa especially useful at the start or end of an Iceland trip. You can build it into a transfer day, though you should allow enough time for check-in and for handling luggage. Staff at The Retreat can help if you need luggage storage.

If you arrive by bus, get off with the other passengers at the Blue Lagoon stop. Walk to the Luggage House, where an attendant can call a shuttle to The Retreat. This is an extra step, but the instructions are clear.

Starting times vary, so check availability before planning the rest of your day. The experience lasts five hours, and that is long enough to shape your schedule around it.

Who should book the Retreat Spa?

I would recommend it most strongly to couples who want a quiet, special day and do not mind paying for privacy. It also suits anyone who values comfort, a private changing room, and a structured spa ritual more than a packed sightseeing schedule.

It is a good fit if you:

• Want a calmer alternative to the main Blue Lagoon setting
• Are marking a birthday, anniversary, or other special occasion
• Need a rest day during an active Iceland trip
• Are arriving from or heading to Keflavík Airport
• Like skincare treatments but prefer applying them at your own pace
• Can accept a strict no-camera and no-electronics policy

I would skip it if you are traveling with young children, want a budget-friendly pool visit, or would rather spend five hours exploring the Reykjanes Peninsula. The age limit also rules out families with children under 12.

The experience has earned a strong overall rating, and the clearest praise is easy to understand: the setting, privacy, and calm are the main attractions. The five-hour format gives you room to enjoy the place rather than squeeze it between other stops.

Final verdict: a luxury choice with a clear purpose

The Blue Lagoon Retreat Spa is worth booking when you want the Blue Lagoon experience with less noise, more personal space, and a full half-day to slow down. The private changing suite, quiet Retreat Lagoon, volcanic interiors, and Blue Lagoon Ritual give the visit more substance than a basic geothermal soak.

I would not call it a bargain. At $724 for two, you need to care about privacy and comfort to feel good about the cost. But for a couple seeking a memorable Iceland splurge, this is a well-defined luxury experience rather than an expensive add-on with little to show for it.
