Rope climbing around Magic Wood Switzerland

Hi,

we're planing to visit MagicWood in Switzerland in the May for the bouldering, and I was also wondering if there are any sport climbing (on rope) crags around the area
in case we get bored from bouldering ;-) Proximity could be up to 20 - 30km from MagicWood.

Thanks.
Best regards.
Dan.
