I created these travel printables for kids in black and white so they won’t kill your printer: travel journal pages, travel games and road trip games.
Designed to keep kids busy and entertained, I recommend these (affiliate link) erasable gel pens by Frixion and a clipboard for each kid to have a hard surface to write on. Note that the ink in these pens is heat sensitive and will disappear.
Travel Journal – print a page for each day of your trip.
