If this part is on the way, you can take the two easy single trails starting at the top of the quarry at the fence. After all, it goes downhill briefly in a few turns and depressions. The starting point is the same for both trails. Shortly after the start it goes left or right. A single trail uphill takes you back to the starting point of the tour. The whole thing can also be combined with an exposure of the quarry. Of course, all of this can be combined with the trail options in nearby Bulau.
