Šmitovo jezero consists of two connected lakes, Small and Veliki. Endemic species live in the lake and the nearby Rupečići cave: manfish (Proteus anguinus) and lamprey fish (Telestes polylepis). A very nice place to visit and rest.

Klečice (1062 m) lives in the shadow of the magnificent Klek but they are certainly worth a visit and views. Caution: the hiking trail is marked only to the foot of the rock. After that there is a cable and the climb is optional. Not for inexperienced hikers, especially in winter.
