If your kids are staying pretty close to home these days, you’re probably looking for healthy ways to get them really physical this summer and keep them fit throughout the rest of the year too. A slackline for kids can help them (and your whole family) improve their balance, build core strength, increase overall fitness, and make for hours of fun play without ever having to leave your backyard.
Because a slackline will push their bravery and wits at first, it’s a great way to introduce even small kids to the idea of zip lines, climbing walls, and other challenging activities that involve both mental and physical strength.
If your kids are on the smaller side, consider a backyard water slide as an awesome option for summer entertainment. And if you’ve got a backyard pool, snag a floating cooler to keep their drinks cool and close at hand.

- Great for adults as well as kids
Cons:- Wood monkey bars can cause blisters

Whether you’re ready as a family to face a serious slackline, one that extends 60 feet is going to present a challenge whether you’re a kid or an adult. This slackline kit goes so much further though because it comes with 13 obstacles and accessories to transform it into a wicked ninja line as well. The two-inch-wide slackline can handle from up to 250 pounds, so we’re talking about serious safety here, no matter your age.
The obstacles can be adjusted to make spacing easier at first and more challenging later. You’ll also get a heavy-duty industrial ratchet that can and should be one of your key must-haves. Obstacles include four gymnastic rings, three monkey bars, and a rope ladder. You can also get an obstacle expansion pack that includes a spinning wheel, two traverse rings, and two monkey fists, all of which can be moved apart to make this course more difficult once your kiddos have experience.
