How about getting him a scratch-off world map? This way he can scratch off all the places he has visited and keep track of where he still wants to go. Another idea could be a travel photo album or a personalized photo book with pictures from his past trips or a gift certificate for a destination he's always wanted to visit. You could also consider buying him a travel guidebook or a subscription to a travel magazine or website to inspire his future adventures. Additionally, a high-quality backpack or luggage with his name or initials on it may come in handy for his travels.
Or you can get him a star map with the date when he was born.
