The King and Queen traditionally host the royal family on the Sandringham estate for Christmas, and their Norfolk abode has already been transformed into a winter wonderland – with an added treat that Prince Louis will love.
For the past few years, the grounds of the royal residence have featured a spectacular festive light trail, Luminate, which is open to the public until 24 December.
And this year's addition will no doubt delight the younger royals, as the Prince and Princess of Wales have previously taken their three children on the festive woodland walk.
As well as exploring the Christmas tree maze and food stalls, visitors can also bring their own marshmallows to toast on the fire pit, as revealed on Sandringham's Instagram account.
Louis, six, was particularly enthusiastic about toasting marshmallows as he carried out his first official royal engagement in 2023.

After helping to move sand in a wheelbarrow and trying his hand at controlling an excavator with his dad, Louis was rewarded with the sweet treat.

Given Kate's role as joint president of the Scouts with the Duke of Kent, the Princess is also quite partial to marshmallow.
