A great anniversary gift idea for your wife who loves backpacking would be a high-quality backpack or hiking gear. Here are some suggestions:
1. A new backpack: Get her a high-quality backpack that is lightweight, durable and has ample storage. You can personalize the backpack by getting it in her favorite color or by having her initials embroidered on it.
2. A water filtration system: For backpacking trips, access to clean water is essential. Give your wife a portable water filtration system that is easy for her to carry on her trips.
3. A trail hammock: A comfy trail hammock will be a great addition to her backpacking gear. She can use it to relax while enjoying the views, and it will also give her a comfortable place to sleep on the trail.
4. A portable camping stove: A portable camping stove that runs on gas or propane will be perfect for your wife to cook her camping meal. It will save her the stress of worrying about what food to eat while she is out backpacking.
5. Portable Waterproof Bluetooth Speaker: Give your wife a waterproof, shockproof and dustproof Bluetooth speaker that she can take with her on her backpacking trips, to listen to her favorite music, podcasts, or audiobooks while on the trail.
Or you can get her a star map with the date of your anniversary.
