An Overview On Slacklines

Tightrope walking has been around for more than a century, but today’s young consumers have put their own spin on it. Slacklining uses a flat surface rather than a rope, but the concept is very similar. You tie each end between two anchoring items, such as trees or poles, and walk from one side to the other.

One of the best things about slacklining is that you can set it up anywhere. Whether you’re on vacation with family or at home entertaining guests, you can find two trees and get started. All you’ll need is your mainline, ratchets and something to protect the trees. Most kits come with everything you need, along with a storage bag to keep it all together.

If you’re new to slacklining, you may want to start with a training line first. These lines are flatter and wider to let you get used to slacklining before advancing to the thinner line. You should also start with your line close to the ground, then gradually move it to a higher position. By doing this, you’ll get practice walking across it without the stress of being well above the ground.

Some slacklines can also easily be turned into ziplines. You can do this if you  purchase a zipline hand brake. You may also want to invest in a pair of gloves designed for ziplining if you plan to use your slackline this way.

Some slacklines are built specifically for dangling rather than walking. These have extra attachments you can purchase, like climbing ropes and wooden bars. It’s a great way to create a playground in your own backyard that will keep both adults and kids entertained. If you’re buying a slackline for exercising or athletic training, you may find this type of slackline keeps you more engaged than if you had only one activity option.

DWYM Fun Fact

Slacklining is believed to have gotten its origins in the 1980s as a pastime for climbers at Yosemite National Park. The practice gradually evolved until climbers began getting attention for taking the sport to the extreme. That attention started in 1985, when one slackliner made national news by crossing a gap in Yosemite Valley on a slackline suspended 2,000 feet from the ground.

In recent years, though, the sport has opened up to even the most casual adventurers, with slacklines that can be strung wherever two trees can be found. But you can also slackline at a competitive level. The sport now has an international federation, numerous contests and Red Bull-sponsored athletes.

The Slackline Buying Guide

  • Slacklines are fun for kids, but they also provide a good workout. You’ll find you not only improve your core strength, but you also develop better posture and concentration.
  • It’s important to only anchor your slackline to trees that are at least one foot in diameter.
  • You’ll find you get more stability the closer the trees are together. If you’re going for a longer slackline, look for one that is built for extra strength and support over greater distances.
  • Make sure any slackline you order comes with the accessories you need to get started. You should have ratchet straps to anchor your slackline in place. An added bonus are tree protectors, especially if you plan to use your slackline often on trees in your own yard.
  • If you plan to use your slackline on trees that are extremely large, you’ll need longer ratchet straps to handle the distance.
  • Newcomers to slacklining may want to choose a kit that includes setup instructions.
  • Another bonus for newbies is a training line. This will help you learn the ropes before progressing to the mainline.
  • Look closely at the capacity of your slackline, especially if you plan to have more than one person at a time on it. Many have a capacity of up to 300 pounds, but you can find some that go even higher.
  • Some slacklines use parachute-style material to provide a little extra bounce. If you plan to do handstands or other tricks on the line, you may like that setup better.
  • Another factor in performing tricks is how tightly you ratchet the line. Many experienced slackliners like to keep the fit a little loose to give them that extra bounce. A tighter line might be best if you’re new to slacklining, though, as it eliminates sway and bounce.
  • Safety is important when you’re slacklining. Check your gear and the line carefully before setting it up, especially after it begins to age. Never leave your line unattended and remove it as soon as you’re finished. It can present a hazard to runners and cyclists who might not see it as they’re passing through.
