Močilnik, is a limestone cove; out of which waters from the springs of Mali and Veliki Močilnik flow to form the river Mala Ljubljanica. The Veliki Močilnik spring is located under a high precipitous wall (40m), named Devil`s rocks. The rock wall contains a hand print which according to legend belongs to Jason. Legend has it that the journey of the Argonauts from the Black Sea ended at the spring, and it was here that they dismantled their ship and carried it on their shoulders to the Adriatic Sea to continue their homeward journey.
