For cross-country skiers the Sonnenberg Langlauf Network (Loipennetz Sonnenberg) offers a direct link to the trails around Sankt Andreasberg. In addition there is a connexion to the Ackerloipe and a link trail to Oderbrück, that runs past Oderteich. For tobogganists there is a separate toboggan piste. Medical support is provided by a first aid station operated by the Sankt Andreasberg Mountain Rescue organisation (Bergwacht Sankt Andreasberg) on the large car park, that is open during winter weekends. Due to its height the Sonnenberg has guaranteed snow until spring.
