Highline Preparation Course – Amsterdam

Hi there!

Are you interested in learning how to highline? Here in the Netherlands, that can be quite challenging. That’s why SlackNED has installed 2 indoor highlines in a boulder gym in Amsterdam!

However, to be allowed on the highline, you need to be able to do a mantle mount and a leash climb. Being able to stand without jumping from the ground is also advisable to make the session more fun. This course is aimed to teach you exactly that!

The course will only happen at least 8 people sign up. You can sign up until 29th of May

Price (highline session included)

  • €55 for SlackNED members*

  • Did you participate in the crowdfunding and chose this as a reward? Then the course is for free!

*Consider becoming a member, the fee is €35/year. You receive discount as well at the indoor highline. Go to www.slackned.nl/wordlid
