I suggest getting your granddaughter a pair of high-quality cross-country skis or ski boots that are specifically designed for her size and skill level. If she already has those, you can consider purchasing ski poles, a ski jacket, or a ski hat. You could also get her a gift card to a local ski shop or a ski resort pass so she can enjoy her favorite sport even more. Another idea is to research and book a guided cross-country skiing tour in a scenic location as a special experience gift.
Or you can get her a star map with the date when she was born.
