The place you describe sounds very much like the surroundings in Bridge to Terabithia. It is one of my absolute favorite movies, despite being more or less a movie meant for children, or at least teenagers. There is a novel, too.
If I lived near fields and woods and fallen tree-bridges I'd spend my whole day there, only sleeping at home.

I'm equally glad that you can relate to what I'm describing. It's very nice to know more people feel the same, and can find that peace outside.
