Slackline Berlin opens its season with a day of lines in the Hasenheide park: 22 lines from beginner and rodeo lines to longlines, plus a spacenet and a shared potluck buffet. It is meant for everyone, from people who have never stood on a slackline to walkers chasing a longline record.
Slackline and longline in a city park, not highline. Starts at 11:00.
