Children's Party at Fort Vertier in Harderwijk

Yay, it’s party time! Time to celebrate the birthday kid in style with friends. At Fort Vertier, kids get to step right into the game themselves. They run, climb, explore, and scan in and around the Roman fort.

You’ll get your own party table, the birthday child will receive a gift, and every child will get a soda, a cool temporary tattoo, and a certificate. And we wrap up every party with a round of laser tag. You pick the date, and we’ll make the adventure happen.

A fortress full of games, puzzles, and action

Ready for the mission? At Fort Vertier, kids step into an outdoor game. They dive into the large Roman-style 3D maze and play various games in and around the fort. They search for the right towers, solve Roman riddles, and scan their wristbands to collect points.

Meanwhile, they run, climb, and scramble through the fort. The screens show them their progress right away. Could they go faster? If so, they simply try again. In between, they exit the fort via the slide, the Big Airbag, or another route—only to take on a new challenge through a different entrance. This keeps the whole group actively engaged.

As a parent, you can relax

While the kids run around the fort, you can sit comfortably nearby. From the picnic tables surrounding the fort, you have a great view of the action without having to chase after them everywhere.

Coffee or tea to go with it, the kids playing outside, and no living room full of crumbs afterward. That’s a treat for parents, too.
