You can access the gravel pit Boršt from the local road Krška vas-Cerklje ob Krki- you turn right (even if Boršt is on the left), drive through the road base and then you'll see the gravel pit on your left - you can drive directly to it.
The gravel pit is currently home to cyprinid species like chub, carp, bleak and to some predatory fish as well.
