ION Adventure Hotel Nesjavellir
iceland, iceland · ★★★★
The Verdict
Worth it for your honeymoon?
ION Adventure Hotel is the design hotel for couples who want their Iceland honeymoon to feel architecturally memorable. The property juts out of a lava field in Nesjavellir — 45 minutes from Reykjavík, on the doorstep of Þingvellir National Park — with a cantilevered concrete-and-glass form that feels like something from a Bond film. Rooms are compact but meticulously designed: blackout drapes, lava-gravel walls, recycled-timber headboards, and huge windows facing a landscape that can shift from green summer moss to white lunar snow in a week. The hotel's Northern Lights Bar is genuinely an attraction — a long glass wing with low lighting, designed for aurora spotting — and the outdoor geothermal pool, carved into the hillside, is one of the most photographed honeymoon moments in the country. Add a kitchen doing confident farm-to-table Icelandic cooking and you have a stylish, scenic base for exploring the south and west.

Your 7-night honeymoon itinerary
Arrival and first pool soak
Transfer from Keflavík (75 minutes), check-in, a welcome cocktail at the Northern Lights Bar, and an evening soak in the geothermal outdoor pool.
Þingvellir and Silfra fissure
Short drive to Þingvellir National Park, a guided snorkel or dive between the tectonic plates at Silfra, and lunch at a lakeside café.
Reykjavík culture day
Day in the capital — Harpa, Hallgrímskirkja, the FlyOver Iceland experience, and dinner at a Reykjavík tasting-menu restaurant before returning to ION.
Golden Circle
Full Golden Circle loop including Geysir and Gullfoss, a stop at Kerið crater, and a late-afternoon return for a sauna and aurora watch.
Snæfellsnes peninsula
Long day trip to the 'Iceland in miniature' peninsula — Kirkjufell mountain, Djúpalónssandur black pebble beach, and the Snæfellsjökull glacier — returning under star-pricked skies.
South Coast waterfalls
Seljalandsfoss, Skógafoss, and Reynisfjara black-sand beach, with an ice-cave or glacier-walk add-on in winter.
Spa and farewell
Slow morning, couples massage in the ION spa, a final soak in the outdoor pool, and a short transfer back to Keflavík.
Honest Assessment
What to know before you book
The hotel is remote — there is no town or walkable dining nearby, so you will drive or use guided transfers for every meal outside the hotel.
Rooms are well designed but not huge; if you want a suite-scale honeymoon footprint, pre-select one of the corner or signature rooms.
The outdoor pool is heated geothermally but the walk to it is cold in winter — bring or borrow a robe and sandals.
