LÖ bloc!

Fat roofs, steep slabs. If that´s all Greek to you, you are exactly right with us here at LÖ bloc.
If the terms slab-sneaker and greasy jurassic limestone are part of your daily usage, you are as well. We boulder. And we offer you a family-friendly place to learn about it and to live it.
It doesn’t matter if you’ve been on dozens of walls or climb up one for the first time.


Special opening hours

For christmas, new year´s eve and new year´s day: LÖ bloc is closed on the 24th, 25th and the 31st of December and opens again on the 1st of January at 3 p.m.

We wish you a quiet, relaxing pre-Christmas season!


In cooperation with the family club Grenzach-Wyhlen we´d like to give children under 3 years of age the opportunity to crawl, play and romp outside the regular opening hours. Parents take care of their children and can boulder at the same time.
They are supported by the LÖ bloc team and an employee of the Grenzach-Wyhlen family club. No advance booking required! Not during the school holidays!


„Bouldering is the best! … i dove, rafted. Flew. I´ve jumped on every extreme sports trend. (…) Nothing beats bouldering!“

(Udo Neumann, Lizenz zum Bouldern, Udini Verlag 2010, S.012)

When bouldering, you climb at jumping height (max. 4,5 m) above soft floor mats. You do not need rope securing, as it is necessary for sport climbing. Therefore, you do not need any other equipment to boulder in the hall besides climbing shoes.
