I bet it's the grave of Gwen and Elyan's father that they're visiting, which is why it's just the two of them, and gives Gwen an excuse to be out of the castle.

Then on the way back Morgana knocks out Elyan and any guards with them and kindnaps Gwen. When Elyan wakes up he makes his way back to Camelot alone and reports what has happened. Hence Gwen being pulled off her horse in the forest, and Arthur's line "Where is she?"
