A great gift idea for your grandma who enjoys orienteering could be a new compass, possibly one with a personalized engraving. You could also consider gifting her a new map case, as she needs this item to safely hold her maps while navigating. Another idea could be to get her a book on orienteering tactics, tips and techniques to help grow her skill set in the activity. Additionally, you could look into finding orienteering events in her area, and surprise her with a registration to one of these events, or even an annual membership to her local orienteering club. Finally, if you have the ability, you could possibly plan a trip with her to a new orienteering location that she hasn't yet explored.
Or you can get her a star map with an important date you share.
