What Is Slacklining?

Slacklining is an activity that requires balancing on a wide piece of webbing that’s set up between two fixed points. Slacklining can be enjoyed as an independent sport or as a group activity. It’s great for the core, encourages agility, and forces both your mind and body to work together as you walk the line. 

Although slacklining is an extreme sport for some, children and beginner slackliners can practice on their own slackline at home. 

Slack Rope Walking vs. Tightrope Walking 

If you’re wondering what the difference is between walking the tightrope and walking along a slack rope, just look at the name! A “slackline” is, well, slack—whereas a tightrope is tight and under a lot of tension. Slacklines are also made of webbing instead of rope or steel cables. 

According to, tightrope walking is considered performance art (usually performed at the circus) while slacklining is an activity or sport that can be set up basically anywhere (i.e. your front or back yard, the beach, a park, etc.) within minutes. 

The Best Slackline 

As you’re browsing the web for a brand-new slackline, there are a few things you’ll need to look out for, including the safety of the slackline (has it undergone any tests? Is it safe for children or beginners to use? Does it include any safety equipment such as a helmet or knee guards?), its rigidity, width (a wider slackline is recommended for beginners), and its weight capacity. 

You should also ensure that the slackline you purchase comes with everything you need to get started, including a mainline, training line, ratchets, arm trainers, tree protectors, and some type of instruction manual.

“We bought this for a family of eight children ages two to 14,” one Amazon reviewer writes. “It was and IS an absolute hit. Every time we visit, each one shows us what they have learned to do: Tricks, balance, and how much their muscles have grown. Even the two-year-old leans over the slackline and calls it her trick. It is a joy to see!”
