Finally something like a rough estimation and indication of Fribourg "home bouldering" at Cousimbert, 12km out of town.
Summer parking is open from May to November. From Fribourg to Le Mouret, left to Zenauva, than up the route de Cousimbert until the first 180° courb. Park there. Follow the dirt road until you see to cairns (steinmann) to your right. Head into the forest.
