Correct, you entered from the south. You know from prior experience that the main path runs from a gate on the south side of the cemetery to a gate on the north side.
The cemetery is a very large place on the inside. Drax heads north and after passing the ornate tomb he saw (decorated with roses and wolves), he hits an east west path that he recognizes and sees north of him the tomb in which he fought the vampire. Heading around this, Drax sees the cemetery fence, running east and curving away to the southwest. Following the fence for a while, Drax goes down hill and up and then downhill again until he is eventually back at the place close to where he fought the werewolf. A little bit further along the fence brings him to the northern gate.
The gate is in a dip between two hills and east of him he sees a steep hill rising south, (the fence running straight east at the base of the incline) atop of which are the back of tombs. There seem to be holes dug into the side of the hill, like giant rat or snake holes, just below the tombs.
On the other side of the gate, the ground is cemented, but it is hard for some reason to make out details.
