How about a gift certificate for a horseback riding adventure? Many stables and ranches offer guided trail rides through picturesque scenery. You could even join him for the ride if you'd like to make it a bonding experience. Alternatively, you could gift your dad some equestrian gear, like a unique riding helmet, a pair of sturdy boots, or a pair of gloves – that would certainly enhance his experience during riding. You could also consider a book about horse breeds or horsemanship, or a personalized saddle blanket.
Or you can get him a star map with the date when he welcomed you in this world.
