I remember a slightly movie from around the 90's. I remember one scene where a blonde headed young teen girl leads a young boy over a wooden plank that on top of a pond our something on the woods. Can any one help me figure this out?

It sounds like a recent film, but that theatrical film was preceded by another version:

Bridge to Terabithia (1985 TV movie)
IMDb synopsis:
Jess Aarons and new girl Leslie Burke create a world of their own and call it Terabithia and pretend to be the king and queen. They return to their magical kingdom every day after school.

However, the girl has brown hair. She is a blonde in the 2007 remake:

So, it might be some other film.
