Whats the show/ movie that a girl travels forward in her future via a house found in the woods?

I saw a movie or show back in the 80's when I was young that I cannot remember.

Its about a young girl that I think is at a family reunion or maybe vacation and wanders off into the woods/ forest and stumbles upon a house that when she comes out of the woods/ forest so many years have past and her parents are really old but she did not age. Not sure if she went into the house or not.

If anyone has any hints as to what it was I would be greatly happy. I don't know any of the characters in the film.
