Princess Ariane, the youngest daughter of the Netherlands’ King Willem-Alexander and Queen Maxima, headed off to her first day of school at Christelijk Gymnasium Sorghvliet in The Hague on Monday. But rather than using a royal escort to drop her off, the 12-year-old royal got to school via the traditional Dutch method — by bike! Like any proud dad, King Willem-Alexander was on-hand to see his daughter off on her big day — and recorded a video of her giving a wave to the camera as she rode her bike to post on Instagram. For her first day, Princess Ariane kept her ensemble simple — sneakers paired with a black jacket and pants, accessorized with a green backpack. Royal Summer!

Although King Willem-Alexander also documented their inaugural rides to the new school — also by bike, of course — the royal parents have chosen to mostly keep their daughters’ personal lives out of the public eye. “The princesses’ school time is private,” said a statement on the family’s website in April, announcing plans for Ariane to attend the high school. “At the express request of the parents, an appeal is made to the media to continue to respect the privacy of their daughters.” Princess Ariane, Princess Catharina-Amalia and Princess Alexia.
