The ski runs here are of a beginner to medium standard, although sometimes not having so much snow cover as the Titlis side due to the south facing aspect. There is another toboggan run from Brunnihütte back down to Ristis. In summer there are a number of walking trails starting from here, including the Walenpfad leading to Bannalp and the Rot Grätli ridge across the mountains to the north and northeast. There are also a number of prepared rock climbing routes ().
