How about giving your son a high-quality camera to help him take better photos for his travel blog? You can also consider a travel journal for him so he can document his travels and experiences. Another thoughtful gift could be a customized passport holder or luggage tag with his blog's name or logo printed on it. You could also consider purchasing a travel guidebook with great reviews or a voucher for a travel photography class that can help enhance his skills to take better photos.
Or you can get him a star map with the date when he was born.
