One idea could be to book him a white water rafting trip with a guide to a place he's never been before. You could also get him a personalized waterproof phone case or dry bag to use while rafting. Another idea could be a GoPro camera to capture all his adventures on the water. You can also get him a book on white water rafting or a decorative map of famous white water rafting spots. Lastly, if your boyfriend is into cooking, you could buy him a smoke infuser and wood chips so he can smoke and barbecue protein at home and while camping.
Or you can get him a star map with an important date you share.
