Outdoor gaming at Fort Vertier in Harderwijk

Open the day after tomorrow from 1:00 PM to 5:00 PM

Have your kids put down their controllers for a moment. At Fort Vertier, they get to be the ones playing the game. Inside and around a large Roman fort, kids ages 5 to 13 run, climb, and search for the right towers.

They scan their wristbands, collect points, and try to beat their high scores. Everything takes place outdoors, with plenty of space to burn off some energy. Meanwhile, you can relax and watch from the picnic tables.

"The 7- and 12-year-olds kept themselves entertained for two hours with the three different types of games they could play. It was especially nice that the questions they were given took their different ages into account."

"This was our first time here, and we weren't quite sure what to expect, but the friendly staff member explained everything clearly, and then the fun could begin! We got to explore the inside of each tower, and then the kids played the next game—this was also clearly explained, and the kids had the absolute best time! At the end, they got a super cool Fort Vertier tattoo, and they had a fantastic adventure! Thanks!"

"My daughter and I really enjoyed your beautifully designed maze. It was a bit tricky for adults to navigate at times, but we found it all quite amusing. It helps to keep your wits about you."
