I’m not very good at relaxing. If there’s nature to be enjoyed, I’m not the type to look passively at it: I swim, hike, ski or bike through it. So the fact that I couldn’t persuade myself to get up off the floor of the Hot Stone Room at Fairmont Chateau Lake Louise’s new BASIN Glacial Waters spa for more than an hour felt like a personal milestone.

The room itself is simple and spare, its floor composed of broad stone-slab beds that radiate steady, calming heat. Unlike a sauna, the temperature isn’t aggressive. At 50 to 60°C, it allows you to drift into a kind of suspended stillness, barely aware of where the warmth ends and your body begins. The only other time I’ve felt such a deep state of relaxation was during a sound bath on a heated waterbed at the Saxon Hotel’s spa in Johannesburg, South Africa.

I had arrived with a degree of skepticism. Many thermal spas I’ve visited feel like elaborate circuits of fancy showers and oversized whirlpool baths – but I was utterly blown away by everything about BASIN Glacial Waters.

The design alone is transporting. It’s part of a transformative $130 million refurbishment investment across the hotel – including the renovation of guest rooms – which culminated in the opening of BASIN in September. Created by Milan-based AD100 architect Matteo Thun – who grew up in the Dolomites – the spa follows his guiding principle that “nature should shape the architecture, not the other way around.” The result is less a building than a quiet meditation on its surroundings.

You enter through a long, gently curving corridor, almost monastic in its calm, punctuated by deep-set semicircular windows. Each frames a slightly different view of Lake Louise’s startling cobalt water. Pale wooden slatted beams – crafted from sustainable Canadian wood – line the walls and ceiling. And crucially, unlike many spas that sequester you from their surroundings, this one opens you up to them. Natural light floods in, and each area – from the saunas to the salt room and therapy pools – has enormous windows looking out at the mountains, the lake and the glacier from which the spa’s water originates.

My original plan had been straightforward: a restorative morning at the spa followed by a hike to immerse myself in the scenery. But somewhere between drifting in the warm thermal pools on the deck in the brilliant alpine sunshine and swimming from the inside of the spa to the outdoors via the infinity pool, my inner A-type voice went quiet.

Instead, I surrendered to the particular pleasure of taking in the hypnotic views while suspended in warm water – a kind of aquatic illusion that allowed me to feel like I was a part of the lake without braving its frigid temperatures.

The most strenuous activity I managed all day was an Aufguss sauna ceremony led by a very enthusiastic Dutchman named Kyan van Haasteren, trained by the Aufguss master Lasse Eriksen (there are, it seems, many possible career paths in life). Until that afternoon, I had never even heard of the Germanic ritual.

It began with the donning of a grey felt hat – counterintuitive at first glance, but it’s designed to insulate the head against extreme heat – before we took our seats in a sauna made of dark-stained Douglas Fir and dominated by a broad platform of heated stones. Standing behind them, Kyan poured essential oil-infused water across the surface, releasing bursts of fragrant steam. Then came the choreography: rhythmic, almost theatrical waves of a towel to circulate the aromatic steam around us and intensify the heat, all while pulsating Spanish music played in the background.

After 15 minutes, we were released into the mountain air to dunk ourselves into the glacial-temperature plunge pool on the deck – a degree or two colder than Lake Louise itself (in which I had done a polar bear swim the morning before).

Later, in the Glacier Lounge, sipping a divine smoothie and nibbling a miniature passion-fruit pavlova (bone broth was also available for the virtuous), I paused to take in the full theatre of the setting: the lake, the mountains, the looming glacier beyond.

It struck me then that what Fairmont had created here felt like something new for Canada – an alpine spa experience that would not feel out of place in Switzerland or Austria, yet it remains entirely rooted in its surroundings. It’s a place where the landscape is not just admired, but quietly absorbed.

This is perhaps why I gave myself permission to return to the Hot Stone Room for one last full-body drift. The hike could wait until tomorrow.
