NWSF is a two day slackline festival in the North of England that boasts a vast and beautiful park as its setting, providing over 20 lines which vary from the classic 10m beginner line, through to 130m longlines. The festival is held with a strong ethos of slackline; working with one another to have fun, learn new things and develop as a community.

Activities range from Trickline, Longline and Speedline competitions, SlackCinema evening, Slackline skills workshops and more.

Spectators need not purchase tickets, only those using the slacklines and entering competitions.
