Perhaps a small part of Hermione would always seek out refuge in the Forest of Dean. She was on the edge of the forest before she even realized were she'd run to. It was instinct that brought her to the same place she and her boys used to hide a lifetime earlier during the blasted horcrux hunt. Knowing that it wasn't safe to head straight into the forest until she knew for certain she had not been followed to the area by her husband, she spent the entire day after leaving Cornwall carefully skirting the edge looking for any indication she was about to be captured again. Only when the sun went down did she enter the forest completely.
