The International Slackline Association was officially founded as a non-profit in August 2015 by a collection of slackliners from around the world who are passionate about the community, sharing resources, and promoting slacklining in all its forms.

The ISA aims to gather all national governing bodies, their regional and local slackline associations and clubs as members.

We have helped develop dozens of events. They act as a place to meet, connect and become a starting point for formal clubs or organization.

Where such structures don’t exist we help to build them from scratch.

The International Slackline Association aims to support and develop slackline communities of all sizes by enhancing communication and informational resources. We support the urban-alpine activity of slacklining as well as competitive slackline sports.
