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 if 10 people sign up, and the closing date for singing up is 1st of September, so be quick to register !

Price (highline session included)

  • €65 for SlackNED members
  • €75 for non SlackNED members
  • Did you participate in the crowdfunding and chose this as a reward? Then the course is for free!

What will you learn?

  • How to leash climb
  • How to mantle mount
  • How to stand on a slackline (knee drop mount, chongo or sit start)
  • If there is time and interest, some rigging basics.

Dates & Time

  • 6th of September 18:00 – 20:00
  • 13th of September 18:00 – 20:00
  • 20th of September 18:00 – 20:00
  • 27th of September (1x highline session!)* 

It’s required to follow at least 2 lessons in the park!

*Depending on the amount of people that join the course, the highline session might be divided among different dates and times. 



It’s better to bring your line and your harness if you have it, but we have a couple one-size-fits-all harness that you can borrow for the course.


The lessons will be guided by the very experienced Jonas Konijnenberg!
