An awesome Christmas present idea for your granddaughter who loves kite surfing would be a kite surfing experience. You could either book a session with a professional instructor or purchase a kit that includes all the necessary equipment needed for kite surfing. Additionally, you could also consider purchasing a book or DVD about kite surfing or getting her some kite surfing themed clothing or accessories to complete the gift.
Or you can get her a star map with an important date you share.
