Playful Hamish, Nobby, Sisu and Luka spent the day rolling about and sliding down the hills of Project Polar.
Project Polar is one of the world’s largest reserves which is at the centre of international conservation efforts to save the species.
Yorkshire Wildlife Park, in Branton near Doncaster, is currently shut due to the pandemic.
The park "offers a unique walk-through experience", allowing visitors the chance to get almost face to face with some of the world’s most beautiful and rare animals.
The park's newest Polar Bears were eager to enjoy the snowy conditions on Thursday.
The three new arrivals continue to settle in well with resident bear Nobby.
