Harderwijk Outdoor Playground

Playing outside in an interactive Roman fort

Are you looking for a fun outdoor playground in Harderwijk? Then you’re probably looking for a place where kids can run, climb, explore, and burn off some energy. At Fort Vertier, they get exactly that—but with a twist.

Fort Vertier isn’t your average playground. Here, kids step right into the game themselves. Inside and around a large Roman fort, they navigate their way through an interactive maze, solve puzzles, and scan their wristbands to track their fastest times. Everything takes place outdoors, while you relax and watch from the picnic tables.

Why Fort Vertier is more fun than a playground

At Fort Vertier, outdoor play is all about action, discovery, and getting lost in the adventure. Children ages 5 to 13 run through the fort, climb and scramble to the right spots, and try to beat their high scores.

They play various games in and around the fort. Sometimes they try to find the right tower, other times they solve puzzles or scan for points. That’s why Fort Vertier is more than just an outdoor playground.
