ICENAVI · BLUE LAGOON HOTEL FIT
The Retreat sits inside the Blue Lagoon complex on the Reykjanes Peninsula, between Keflavík International Airport and Reykjavík. The address removes a transfer after the spa, but it does not remove flight buffers or the need to plan the next drive. Compare one night, two nights and a day visit by the time you can actually spend on site.
ICENAVI HOTEL FIT · THE RETREAT
Start with How Much Time You’ll Actually Spend at The Retreat
Only factors that change the stay decision are scored.
Stay includes Retreat Spa, Retreat Lagoon, Blue Lagoon, and breakfast, ideal for a full day on-site.
Closer to KEF than the city center, but you still need buffer for flights, transfers, and road conditions.
40–60 sqm suites are sufficient for two guests; private lagoon suites only make sense if in-room time is the main focus.
Rates carry a significant luxury premium; included amenities don't offset the cost for every traveler.
Main experiences are on-site, so rain doesn't stop activities; flights and roads remain external constraints.

The Retreat is built into the ancient lava flows on the south bank of Blue Lagoon. The hotel has 60 suites ranging from 40 to 230 square meters. Room rates include access to the Retreat Spa, Retreat Lagoon, Blue Lagoon, à la carte breakfast, Wi-Fi, minibar, and fitness center. These inclusions create a specific stay logic: after checking in in the afternoon, you can stop driving and schedule spa treatments, dinner, and room rest in one place.
Compared to a typical Blue Lagoon day trip, a common waste of time is having to move luggage with wet hair, rush to a transfer, or drive back to Reykjavik after soaking. Staying at The Retreat doesn't save you a "free spa" in a magical sense; it saves you one transfer, one luggage storage hassle, and allows you to spend the two or three hours after soaking in your room. This benefit only holds if you actually stay.
Arrival Night or Departure Night: When Does The Retreat Fit Best?
| Your Itinerary | What the Stay Saves You | Most Likely Waste | Route Fit |
|---|---|---|---|
| Arrive KEF in afternoon, start ring road next day | Direct transfer from airport to Blue Lagoon complex, depart next day | Flight delays shorten Spa time | Choose only if flight arrives before noon and you accept high rates |
| Night before departure, still want to soak in morning | No need to return to Reykjavik early morning | Early flights still require car return and security buffer | More reasonable if flight is later and you want to stay in complex on last day |
| Already booked Blue Lagoon day pass, return to city at night | Almost nothing; day experience is already the main event | Paying high rate for just a bed | Staying in Keflavík or city is more practical |
| Two days dedicated to spa | No repeated commuting; room becomes rest area | Booking one night but scheduling external sights | Two nights needed to fully use suite and Spa |
If this is your first time in Iceland and you need to pick up a rental car and drive long distances after landing, I wouldn't treat The Retreat as a "casual overnight." Landing, car pickup, volcanic peninsula roads, check-in, and Spa bookings all eat into time. Conversely, if your departure flight is after noon, the hotel allows your last day to avoid cross-city travel, making this location advantage easier to utilize. For an early flight, verify the actual transfer or self-drive plan to KEF rather than relying on straight-line map distance.
Room Types and Rates: What Are You Actually Paying More For?
The official 2026 rate card lists Lava View Junior Suite, Moss Junior Suite, Lagoon View Junior Suite, Moss Suite, Lagoon Suite, and Blue Lagoon Suite. The 40 sqm Junior Suite is the entry level; 60 sqm suites offer more space, a terrace, and a stronger sense of in-room stay. The 230 sqm two-story Blue Lagoon Suite features a private lagoon, private Spa, and butler service, placing it in a different price bracket. The rate card also specifies: Lava View Junior Suite has a one-night rate, while other suites usually have a two-night minimum stay requirement.
| Room Type | Official 2026 Approx. Rate (ISK/Night) | Approx. HKD/TWD | Time You're Buying |
|---|---|---|---|
| Lava/Moss Junior Suite 40㎡ | From 230,000; one-night option from ~250,000 | ~HK$13,500–18,000 / NT$55,000–73,000 | Want to try complex stay, low in-room requirements |
| Lagoon View Junior Suite 40㎡ | From 280,000 | ~HK$16,500 / NT$67,000 | Willing to pay extra for water view and terrace |
| Moss Suite/Lagoon Suite 60㎡ | From 315,000 / 440,000 | ~HK$18,500–26,000 / NT$76,000–106,000 | Two-night itinerary, will spend more time in room |
| Blue Lagoon Suite 230㎡ | From 2,500,000 | ~HK$147,000 / NT$600,000 | Private lagoon and butler are the main journey highlights |
Conversions use approximate rates of 1 HKD = 17 ISK and 1 TWD = 4.2 ISK, intended only for budgeting context, not payment quotes. Summer, Christmas/New Year, views, and minimum stay nights will change total costs. For two people, the difference between a Junior Suite and a city hotel can be several times; if the saved time is only worth half an afternoon, don't convince yourself with "many amenities included."
Blue Lagoon entry and Retreat Spa are separate parts of the stay
Guests include access to the Retreat Spa and Retreat Lagoon, as well as Blue Lagoon. The Retreat Spa is built underground, featuring dry heat, steam, cold water, rest areas, a viewing platform, and Blue Lagoon Rituals. The Retreat Lagoon is the hotel's more private water area. These details make the stay decision different from a day pass: buying only a Blue Lagoon ticket focuses on time in the water; staying at The Retreat focuses on breaking a day into multiple segments, without needing to complete all experiences in one entry slot.
If you're still choosing between Blue Lagoon and Sky Lagoon, read The Real Trade-offs Between Blue Lagoon and Sky Lagoon first. Once you've decided on Blue Lagoon, the next question becomes "just go once" vs. "hand over the whole night to the complex." This page answers the latter, not treating The Retreat's stay price as a substitute for attraction tickets.
Dining, Room Time, and the No-TV Trade-Off
The hotel has the Moss restaurant, officially led by Aggi Sverrisson, typically open Wednesday to Sunday with last seating around 21:15. Dinner requires a reservation; don't plan on finding a table after check-in. If you've just finished a long drive, the restaurant on-site saves the effort of driving again. If you just want a simple bowl of soup noodles, the dining style and prices here may not meet expectations.
Suites do not have TVs. This is not a marketing point of pro or con, but a room condition that changes the experience. If your budget includes resting in the room, viewing lava scenery, soaking, and sleeping, no TV won't affect your itinerary. If you're bringing children or need to work in the room, know this in advance. Lower-level rooms are adjacent to water areas; official rate data specifies that children aged 8 or under cannot stay in lower-level suites with direct water access. Family bookings must check specific category and age rules.
The Retreat vs Keflavík or Reykjavík: Choose by Flight and Route Timing
Keflavík hotels mainly handle flight buffers, car pickup/return, and early flights. Reykjavik stays handle restaurants, museums, city activity hubs, and car-free nights. The Retreat's job is to turn a Blue Lagoon day into a stay day. None wins in all itineraries; the judgment lies in your next hard time constraint.
| Base | Less Travel | Cost to Pay | When I'd Choose It |
|---|---|---|---|
| The Retreat | No luggage moving or city return after soaking | Very high rates, must keep activities on-site | Blue Lagoon is the main journey highlight, with full half-day to day |
| Keflavík | Airport transfer for arrival/departure | Must arrange Blue Lagoon transfer or self-drive separately | Early/late flights, or just need a clean night |
| Reykjavik | City dining, meetings, and walking | Round-trip drive to Blue Lagoon | City itinerary is the main body, Blue Lagoon is just a half-day activity |
If you're heading straight to the Golden Circle or South Coast the next day, The Retreat is not the smoothest first base for a ring road trip; you must first return from the peninsula to Route 1. This connects to Arrival and Departure Split for Staying Near Blue Lagoon, then choose "rest after soaking" or "hit the road next day" based on your route. If you only have two days, Reykjavik and Blue Lagoon Two-Day Plan puts city nights and soaking days on the same timeline, making it easier to see if the stay price difference is worth it.
Five Questions to Answer Before You Book
- Does your flight arrival time leave enough buffer for car pickup, luggage, and check-in?
- Can you truly use a full day across Spa, lagoon, and breakfast?
- Are you choosing a Junior Suite that allows one night, or a suite with a two-night minimum?
- Does Moss dinner require a reservation, and can your arrival time make it?
- Are departure day flights, car return, roads, and transfer times harder constraints than soaking?
The reason The Retreat is worth staying is not the word "luxury," but that it turns an attraction day requiring bookings, changing clothes, storage, and transfers into a rest day without leaving the complex. If you just want to check off Blue Lagoon, staying will amplify unnecessary room costs. If you want your last night to slow down, Spa, dinner, breakfast, and airport direction form a complete path.
Is Blue Lagoon already your main course?

Q&A | The Retreat at Blue Lagoon
Is The Retreat suitable for just one night?
Only specific categories like the Lava View Junior Suite have a one-night option; other suites usually have a two-night minimum stay requirement. If staying one night, ensure you can truly use the Spa and lagoon.
Does the room rate include Blue Lagoon?
Official stay data lists inclusions of Retreat Spa, Retreat Lagoon, Blue Lagoon, and à la carte breakfast; specific experiences, dining, and treatments must be checked against booking terms.
Is it convenient to go to KEF Airport from the hotel?
The hotel is on the Reykjanes Peninsula, directionally closer to KEF than Reykjavik; actual drive time, car return, transfers, and flight buffers must be calculated separately by date.
Is the cheapest suite sufficient?
If the main course is Spa and lagoon, the 40 sqm Junior Suite can complete the main stay function; only if you'll spend long hours in the room is there a reason to compare 60 sqm or private lagoon suites.
Can I bring children?
Suite categories have different water and age conditions; official data lists that children aged 8 or under cannot stay in lower-level suites with direct water access. Check specific room type rules before booking.
