Slackline is a sport of balancing on a thin tape suspended between two points. It is a a low tension tape so it can deflect in different directions. So be vigilant and balance your body so as not to lose contact with the tape. At first glance, slackline is very similar to tightrope walking, but in reality the sports have little in common. Ropes intended for walking at heights are tensioned in such a way as to eliminate any deflection. The tape, on the other hand, depending on its intended use, is characterised by different elasticity and dynamics.


Slack is divided into several types and the most popular are:


– a walk on risers suspended high above the ground. It is the most spectacular variety of slack. The tapes are stretched at impressive heights between rocks, buildings and trees. For this reason, walking over them is carried out only with the use of a security harness and lanyard/cowstails.


– impressive acrobatics that resemble jumping on a trampoline. They are made on a tightly stretched tape.


– balancing on tapes longer than 30 meters. It is characterised by large vertical and horizontal fluctuations, which boils down to the principle that the longer and looser the tape, the more difficult it is to pass.


– walking on a tape suspended above the water. The hardest part here is keeping the point of focus. This difficulty is caused by the constant movement of water which affects perception.
