How about a hiking and camping guidebook for a nearby park or area that he hasn't explored yet? You could also create a personalized hiking trail map with all his favorite hikes and some new ones to explore. Another option is to get him a topographic map of his favorite hiking area or a waterproof and durable hiking backpack that he can use to carry his gear and snacks for hiking with kids. For something more sentimental, you could make a scrapbook or photo album of his favorite hiking memories with the kids.
Or you can get him a star map with the date when he was born.
