• Height decides the course, not age: Explorer routes from 90cm, Mini from 110cm, kids' routes from 130cm and every route from 150cm, measured in shoes
• An adult climbs along on the Mini routes, and with under-12s on the medium routes, so book an escort ticket for yourself
• Closed shoes only, since sandals, Crocs and flip-flops are not allowed, and dress warm for a spring or fall climb

A treetop rope park in the Amsterdamse Bos, with 10 courses strung between the trees at different heights. Kids stay clipped to a safety cable from start to finish while they cross rope bridges, a slackline and ziplines.

The easiest routes start 2.5 meters off the ground; the hardest ends with a free fall. Parents who don't climb can walk the paths underneath and cheer.
