ION Adventure Hotel

I was sitting with an active volcano behind me. That is not a sentence you write from many places in the world — and it is not something you forget quickly.

ION Adventure Hotel sits in a landscape of extraordinary power: lava fields, geothermal waters, and a remoteness that feels earned rather than manufactured. Iceland has no shortage of dramatic settings, but ION occupies one of the most visceral — close enough to Þingvellir National Park and the Golden Circle to be accessible, far enough from everything else to feel genuinely removed from the world.

The People First

What stood out most during my visit was not the architecture, or the pool, or the views — though all of those are remarkable. It was the people.

The staff at ION are genuinely invested in your experience in a way that goes beyond trained hospitality. There is a strong sense of unity here — a collective willingness to help that does not feel procedural. If something is important to you, it becomes important to them. That quality is harder to find than it sounds, and it is what transforms a stay from impressive to memorable.

Architecture That Earns Its Place

ION was built entirely with reused materials — thoughtfully so, not as a workaround but as a deliberate architectural choice. The building integrates into the lava field landscape rather than sitting on top of it. That distinction matters. A great deal of so-called sustainable design still announces itself, still competes with its surroundings. ION does not. It belongs totally to the place it occupies.

The rooms are designed for you to actually stay in them. That sounds obvious until you realise how rarely it is true — how many hotel rooms are designed for the photograph rather than the person. Here, the proportions, the light, the positioning relative to the landscape outside all encourage you to remain, to settle, to look. The rooms work because the view works, and because someone understood that the two need to be in conversation.

The bar area is extraordinary, with towering glass walls showcasing the vast, uninterrupted Icelandic landscape, stretching to the horizon with no human intervention in sight. 

I honestly think ION is even more extraordinary in winter, and particularly in March. The snow brings a brightness and a reflective quality to the glass that changes the entire character of the interior — the light bounces, the outside world presses in, and even from indoors you feel the sun in a way that regularly, almost inevitably, pulls you outside to walk in the surroundings. That invitation — from the warmth of the interior toward the cold of the landscape — is one of the things this property does that almost no other manages.

The Pool in March

The geothermal pool at ION deserves its own mention — and a specific one, because the experience of it is very different from the standard luxury hotel pool, and very different again depending on when you visit.

In March, getting to the pool requires you to walk outside in your swimwear through cold Icelandic air. That short walk is part of the experience. By the time you reach the water's edge, your body is already aware of the contrast that is coming.

The pool is low — deliberately so, accessible to everyone — and the moment you step in, the heat is immediate and total. The steam rises around you. The sulphur scent of the geothermal water reaches you before the warmth does. The views across the lava field stretch to the horizon. The cold air above the waterline keeps you alert to every sensation at once.

It activates all of your senses simultaneously: the heat below, the cold above, the volcanic smell, the steam, the silence of the landscape, the strangeness of being warm in a place that looks like the surface of another planet. It is stimulating and calming in equal measure — which is a combination that geothermal bathing seems uniquely capable of producing.

It is a very liberating experience. One I would return for on its own.

A Place That Asks You to Slow Down

Places like ION have a way of doing something increasingly rare: they slow you down. Not through programming or wellness itineraries, but through the sheer scale of the landscape around them. In a setting this powerful, you cannot remain distracted. The volcano is behind you. The geothermal field is in front of you. Iceland does not allow you to be anywhere other than where you are.

I am grateful for experiences that remind you to pause, to look, and to appreciate both nature and the people who make these moments possible.
