Another idea could be to put together a backpacking kit that includes things like a portable water filter, a durable camping stove, and camping cookware. You could also consider getting her a comfortable and warm sleeping bag or a lightweight and compact tent. Lastly, you could consider getting her a book about backpacking with tips and tricks or memoirs of other backpackers for her to enjoy during her trips.
