Ključ (623 m) is a wooded peak between the Horjul and Prosca valleys, with a hut on top, which is open on weekends. Walks along its gentle paths are particularly pleasant on a hot day, since the quiet trails are shaded by trees. Access: From Babna Gora the trail traverses the meadows and runs along the edge of Dolenja vas. On reaching the forest, it rises gently, passing a memorial to a fallen partisan. The path from the Prosca valley is similar, only a bit shorter. The starting point is in the direction of Dolenja vas Zaklanec, left from the road below the Rožnik farm. The path from Brezje near Dobrova is the shortest. Though meandering upwards, it is not too steep. The hut is close to the summit, where you can get the Polhov Gradec Mountain Trail stamp. The trails from Babna Gora to Prosca are part of the Polhov Gradec Mountain Trail. Duration of tour
: 2 hours from Babna Gora; 1 hour from Prosca, 20 minutes from Brezje.
