Nicole Kidman's addictive thriller about a mysterious wellness retreat is back, with the show returning to today.

season 2 sees Kidman reprise her role as Russian health guru Masha Dmitrichenko, while a will play the various guests looking to solve their problems on a wellness getaway.

Schitt's Creek star Annie Murphy, The Good Wife's Christine Baranski and The White Lotus' Murray Bartlett are all joining the cast of the show, based on Liane Moriarty's best-selling novel.

While season 1 took place in sunny California, this time we are heading to the snowy peaks of the Austrian Alps to meet nine new perfect strangers. But where did the filming for Nine Perfect Strangers take place?

Nine Perfect Strangers season 1 is set in California, but it was filmed in Australia. The main filming location was Byron Bay, New South Wales.

The first season of Nine Perfect Strangers ended with Masha driving away in a yellow Lamborghini, leaving her retreat, Tranquillium House, behind.

She left it in the hands of guests Ben (Melvin Gregg) and Jessica Chandler (Samara Weaving) in a surprising turn of events.

Masha appears to have settled in a new location: Zauberwald, her new retreat hidden in the Austrian Alps.

Unlike season 1, the second season is set in the same place it is filmed, with location manager Florian Kuthe telling : "This season shifts scenery from Tranquillum House in the summery Californian forest to Zauberwald in the snowy European mountains, which obviously brings an exciting change in both look and feel of it.

"The world of the mountains gives us a lot to discover, from icy cold forests and snowfields to warm and welcoming interiors, from grand historic architecture to top-notch design wellness amenities, from old cobblestone streets to most elegant palace ballrooms."

While not all of the facilities we see on screen are part of one real place, Masha's Austrian retreat, Zauberwald, was largely filmed at the same private property in the Austrian Alps.

Kuthe told the same publication that he instantly knew the property was what they had been searching for when he saw it.

"I remember fondly when scouting the main property for the first time I just felt overwhelmed by the scenery in the best way possible," he explained.

"Visually, how the estate was sitting between the mountains, the fresh air, the richness in history of the place... It was like you could sense it all.

"Next to ticking just a lot of the boxes we had set when envisioning the retreat, I think as soon as we got there with our directors and producers, they all felt it as well, realising: 'This is exceptional and we have to film here.'"

The Austrian Alps provided the main filming location for both the Zauberwald property and other scenes outside of it. Schloss Leopoldskron, a grand palace in Salzburg, was also used.

Filming also took place in Hotel Krallerhof, Leogang, to develop Zauberwald's facilities, including the property's Atmosphere Spa.

Meanwhile, the cabins overlooking Zauberwald's castle grounds were filmed at Gradonna Mountain Resort in Kals Großglockner.

The Alpine Village of Hallstatt was also used for filming a funicular ride, while they travelled to Obersee, Tyrol to film a scene at a frozen lake.

Nine Perfect Strangers season 2 is available to stream now on Prime Video.
