Every year, slackliners from all over the world gather at Lake Cauma in Flims. This is also a participatory event for movement enthusiasts. Spectators are warmly welcome to enjoy the spectacle.
For participants: On land, short slacklines are available for everyone. In the afternoon, there will also be juggling and AcroYoga. Comfortable sportswear is recommended. Just ask on site if you want to join in.
Beginners interested in the waterlines over Lake Cauma are asked to contact the organizers in advance. There will be some easier slacklines/waterlines over the lake. Participation is at your own risk. You do not need to bring your own slacklines.
For spectators: Around Lake Cauma you have the best view of the spectacle. While some will attempt to cross the lake without falling, others will show their tricks. On Friday afternoon, there will be a race on the waterlines (= Speedline). The spectacle can be seen from all sides of the lake.
For slackliners / waterliners: The water- and midlines will be set up by the organizers. There will be several long waterlines (80–150+ meters) as well as some slacklines on land.
It is recommended to bring warm, windproof clothing, a swimsuit, and a wetsuit – Flims is located at 1000 m above sea level, so it can get chilly. Please also bring your own climbing harness for the highlines. Important: Hearing protection (e.g. earplugs, Buff, etc.) is recommended to prevent ruptured eardrums in case of falls onto the water surface.
