On Thursday 28.5.2015 my husband and I wanted to walk the geological educational trail as we wanted to see the rocks that Kozjanski park presents in its prospectus - Geological educational trail. Unfortunately we were disappointed as part of the trail is overgrown and impassable.
The start was promising until we reached the meadow, where it was uncut (trail) and fenced with a fence (by shepherd) and on which sheep were grazing.

In tall grass we found a post with number 12, which marks the trail; however nowhere was it possible to cross to continue the trail (even locals told that the trail is not maintained). We returned to the starting point to the church of Our Lady on Pesek. We nevertheless continued the trail towards monastery Olimje and further towards "witch". Here also there were no information boards for trail continuation.

For trail continuation we inquired at the ticket seller. This part of the trail is accessible partly by macadam, partly by asphalted road. Information boards are partly overgrown and damaged so that not all rocks are on display.
If someone would like to walk this trail I recommend start at monastery Olimje and continuation by road to "witch" and return back past quarry and follow information boards which mark path to chocolate factory and monastery.
Kozjanski park however, if it undertakes project and promotes it, let it take care that trail will be maintained!
