To get to Kal follow the instructions for Klobuk, except when you reach the tunnel just follow the road for another few hundred meters and park in front of thehut on Kal.

 

Behind the hut you will find the blazes for Mrzlica that is some 200 meters higher. I am mentioning this as you will probably be surpries by the path that goes down instead of up. But don't worry it will yoon get steep, just when you're out of the forest and reach the Mrzlica slopes.

 

Soon you will see the antenna on top and from the top there's just 5 minutes to the hut which is open all year round so you won't be thursty or hungry. 

 

On your way back you can also visit the top of Kal and Klobuk. Just the hike from Kal to Mrzlica will take you about 40 minutes in one direction.
