Welcome to BoulderCenter Grenzach-Wyhlen – your bouldering gym in the tri-border area, only about 20 minutes from Basel. Across 1,200 m² of bouldering surface you will find around 300 boulder problems in 8 grades, plus a children’s area, a training zone, a sauna and a lounge. Thanks to 24/7 access you can climb around the clock – early in the morning, late at night and at weekends. Free parking is available directly in front of the hall.
Coming from Switzerland or France? Our Getting here page has directions and everything you need to know. First time with us? Then our FAQ will help.
Important information for families: for every 2 children, one parent or guardian must accompany and supervise them in the hall at all times. That person is welcome to climb near the children, provided the children behave accordingly.
