The Retreat at Blue Lagoon Iceland
iceland, iceland · ★★★★★
The Verdict
Worth it for your honeymoon?
The Retreat at Blue Lagoon is Iceland's most ambitious luxury property and the clearest honeymoon answer on the island: 62 suites carved directly into an 800-year-old lava field, with private access to a milky-blue geothermal lagoon that guests never have to share with day visitors. The architecture is restrained and almost monastic — volcanic stone, pale oak, floor-to-ceiling glass facing moss-covered rock — and every suite opens onto the same surreal landscape. Couples come here for the Retreat Spa's five-step Blue Lagoon Ritual (a subterranean sequence through lava tunnels, silica masks, algae wraps, and warm mineral baths), for dinner at the Michelin-recognized Moss restaurant with its tasting menu and volcanic wine cellar, and for the rare feeling of having one of the world's most photographed spas essentially to themselves after the gates close to the public lagoon.

Day by Day
Your 7-night honeymoon itinerary
Arrival and first float
Private transfer from Keflavík (20 minutes), suite check-in with champagne, and a slow late-afternoon float in the private Retreat Lagoon as steam rises over the lava field.
The Blue Lagoon Ritual
Spend the morning in the subterranean spa completing the five-step ritual — silica, algae, minerals, sauna, steam — then an unhurried lunch at Spa Restaurant and an in-suite massage before dinner at Moss.
Reykjavík day trip
Guided half-day in the capital — Harpa, Hallgrímskirkja, and a tasting at a small-batch distillery — then back to the Retreat for a sunset lagoon soak and fireside cocktails.
Golden Circle by private guide
A full day covering Þingvellir National Park, Geysir, and Gullfoss waterfall with a private driver-guide, lunch at a tomato farm, and return for a late dinner in your suite.
South Coast waterfalls and black sand
Seljalandsfoss, Skógafoss, Reynisfjara black-sand beach, and Sólheimajökull glacier edge, with a riverside lunch and optional glacier walk for the adventurous.
Spa day and Moss tasting menu
A deliberately empty day — in-room breakfast, long lagoon floats, couples massage in the spa's private suite, and the full tasting menu at Moss with paired Icelandic and Burgundian wines.
Aurora or farewell float
In winter, an aurora-chase excursion with the resident guide; in summer, a midnight-sun kayak on a nearby fjord. Return for a final lagoon soak before departure.
Honest Assessment
What to know before you book
Iceland is extraordinarily expensive — expect to budget an additional $200 to $300 per person per day for food, tours, and transfers on top of the already premium room rate.
Winter days are very short (four to five hours of daylight in December), which is romantic but limits sightseeing and can mean weather-related tour cancellations.
The Retreat is 45 minutes from Reykjavík and not walkable to anything; you will rely on hotel shuttles, private guides, or a rental car for every outing.

FAQ
Frequently asked questions
Is this hotel good for honeymooners?
Exceptionally so. The Retreat is adults-only, has only 62 suites, grants exclusive access to a private geothermal lagoon, and its Moss restaurant and subterranean spa are the most romantic pairing in the country.
What is the best time to visit?
Late September through early March for northern lights and empty landscapes; June and July for the midnight sun and long hiking days. May and September are quiet shoulder-season sweet spots with mild weather and lower rates.
What should we book in advance?
A Lagoon Suite (they sell out six to nine months ahead), a dinner reservation at Moss, the Blue Lagoon Ritual, and any Golden Circle or South Coast private tours. Aurora tours should be booked on arrival based on forecasts.
Is it adults-only?
Yes. The Retreat at Blue Lagoon is strictly adults-only (guests must be 12 or older, with many policies effectively treating it as 18+ on the Retreat Lagoon), which keeps the atmosphere calm and spa-focused throughout.
What's the best room type for a honeymoon?
The Lagoon Suite is the honeymoon benchmark — direct private-lagoon access from your terrace. If the budget stretches, the Retreat Suite adds a separate living room and a panoramic moss-and-lava view.
How do we get there?
Fly into Keflavík International (KEF); the hotel is a 20-minute private transfer away, which the concierge can arrange. Reykjavík is 45 minutes north by road.
