Prince George and Princess Charlotte hit the slopes in the French Alps last week with their parents, Prince William and Duchess Kate.
Kensington Palace's official Instagram account released photos of the family having fun in the snow. One photo shows William and Kate having a snowball fight, while others show George, 2, and Charlotte, 10 months, in their ski bunny outfits.
Charlotte wore a pink hat, pink snow boots and a white snowsuit with matching mittens, while George wore a red hat with his navy blue snowsuit.
The vacation was a big moment for the family, as it was their first holiday as a family of four, and the first time either George or Charlotte had played in the snow.
The trip was brief and the first time since George's birth that William and Kate had taken a ski trip together.
