From Keflavík International Airport (KEF): drive Route 41 east to Reykjavík, then Route 1 and Route 360 toward Þingvellir and Nesjavellir — approximately 90 minutes from the airport. A rental car is strongly recommended for the Golden Circle and hotel access. The hotel can advise on road conditions — Route 360 may require 4WD in winter.

Experience highlights
What a stay here actually feels like.
01
Northern lights from the hot tub
Outdoor geothermal hot tubs at the lava cliff edge, positioned for north-facing aurora viewing — the defining ION experience from October through March.
02
Silfra tectonic dive
Float between the North American and Eurasian plates in 100-metre visibility glacial water — the most extraordinary dive site in Iceland, 20 minutes from the hotel.
03
Lava-edge design architecture
The glass-and-steel hotel appearing to float above the black Mid-Atlantic Ridge lava — one of Iceland's most photographed pieces of hospitality architecture.
04
Lake Thingvallavatn room view
Floor-to-ceiling glass framing Iceland's largest natural lake and the Þingvellir rift valley — the room view that makes ION's architectural ambition explicit.

Your journey
Drive the lava road
The Nesjavellir road is one of Iceland's most dramatic: black lava fields, Nesjavellir geothermal steam columns rising from the earth, and the hotel appearing at the cliff edge above the lake.
Outdoor hot tub at dusk
Geothermal hot water, 38°C, at the cliff edge above Lake Thingvallavatn — the Icelandic sky beginning to darken in autumn, the aurora probability rising.
Northern lights from the tub
The aurora alert arrives. The hot tub faces north. The green band builds and develops overhead. This is the ION experience at its most complete.
Silfra morning dive
20 minutes from the hotel: drysuits on, float between two continents in 2°C crystal-clear glacial water with 100-metre visibility. The North American and Eurasian plates are visible simultaneously from the Silfra Hall.
Geothermal spa recovery
After the dive: the ION Spa's lava stone massage and geothermal pool — volcanic heat applied by hand, the same energy source that runs the Nesjavellir power plant visible outside the window.
About
About this getaway
ION Adventure Hotel is a design hotel and wellness retreat on the shores of Lake Thingvallavatn in the Þingvellir (Thingvellir) National Park corridor, 45 km east of Reykjavík — built into the volcanic lava field on the Mid-Atlantic Ridge where the North American and Eurasian tectonic plates meet. The hotel occupies a dramatic site above Iceland's largest natural lake, with panoramic views of the surrounding geothermal landscape, and is designed to deliver total Icelandic nature immersion with spa and wellness programming grounded in Iceland's geothermal environment.
The architecture is striking: a steel and glass structure that appears to float above the lava field on wooden and steel supports, extending across the cliff edge above the lake with floor-to-ceiling glass walls in every room framing the volcanic landscape and northern lights (in season). The building is designed to disappear into the black lava and silver lichen background rather than compete with it.
The ION Spa uses Iceland's geothermal resources: geothermal water pools, lava stone treatments, volcanic mud scrubs, and the natural thermal energy of the Mid-Atlantic Ridge landscape. The northern lights observatory and outdoor hot tubs positioned for aurora viewing are the property's signature winter amenities. Adventure programming — Northern Lights tours, glacier hiking, caving in lava tubes, scuba diving between the tectonic plates, and Þingvellir National Park hiking — places ION among the most activity-forward wellness hotels in Iceland.
The site that became ION Adventure Hotel was known before the hotel existed: the lava field above Lake Thingvallavatn on the Nesjavellir geothermal road, with the lake spreading southwest and Þingvellir's UNESCO rift valley just beyond the horizon. Architect Minarc chose to build with the lava rather than against it — minimal ground contact, maximum visual connection to the volcanic landscape.

FAQ
Good to know
What is Silfra and why is it famous?
Silfra is a fissure in Lake Thingvallavatn in Þingvellir National Park — the underwater gap between the North American and Eurasian tectonic plates. The water is glacial runoff filtered through lava for 30–100 years, producing visibility of 100 metres or more (some of the clearest fresh water in the world). Snorkeling between the two continents in 2°C crystal-clear water is one of Iceland's most extraordinary experiences — accessible from ION in 20 minutes.
What are the northern lights like from ION Adventure Hotel?
ION's position in the Þingvellir area, away from Reykjavík's light pollution, gives it one of the better light pollution profiles of any hotel in the Golden Circle corridor. The outdoor hot tubs are positioned for upward sky viewing. Aurora alerts are provided to guests on forecast nights. The key factor for northern lights is geomagnetic activity (Kp index 3+) and clear skies — Iceland's weather is variable, and no hotel can guarantee the lights, but ION gives you the best conditions in the region.
How far is ION Adventure Hotel from Reykjavík?
ION is approximately 45 km east of Reykjavík on the Nesjavellir road — typically 45–60 minutes by car depending on conditions. The hotel is positioned perfectly for a Golden Circle base: Þingvellir (10 min), Laugarvatn Fontana geothermal baths (30 min), Geysir (45 min), and Gullfoss (55 min) are all accessible as day drives.
What is Þingvellir National Park?
Þingvellir (Thingvellir) is Iceland's only UNESCO World Heritage Site — and one of the most geologically and historically significant landscapes in the world. It is where the Althing (Iceland's parliament) was established in 930 CE, the oldest parliament in the world, and where the North American and Eurasian tectonic plates visibly separate across a rift valley. The lake (Thingvallavatn, Iceland's largest) and the rift geology are equally remarkable.
What is the ION Spa?
The ION Spa draws on Iceland's geothermal landscape: heated geothermal water in therapy pools, volcanic mud body wraps, lava stone massage, and treatments using local Icelandic botanicals (arctic thyme, angelica, birch). The spa building has views of the lava field and lake, and the outdoor geothermal pool extends toward the cliff edge.
