One day excursion included hiking to the lodge in Stambulcic to the Novak's cave at the mount of Romanija. Orienteering competition was done at the section at Stambulcic, and ski track was located near the hotel where the Lodge of the Faculty of Physical Education is situated. All trails are in the mountain environment and can serve not only to climbers, scouts, athletes (for preparation periods), for recreation, but also to the students during the educational activities in nature.
