How about a personalized climbing gear or accessories for your wife? You can start by purchasing a new harness with her favorite color and get it personalized with her name. In addition, you can give her a climbing chalk bag that reflects her personality, and make it more special by adding a romantic note inside the bag. A book on climbing techniques and routes could also be a great idea so that you two can go through it together and plan your next climbing excursion. Lastly, for a more luxurious gift, you may want to consider personalized climbing shoes with her name engraved.
Or you can get her a star map with the date of your anniversary.
