Twilight filmed at Silver Falls State Park. The mossy old-growth trails used for the woodland and meadow scenes. On screen it's The forest around Forks.
Probable Named in published production coverage; the coordinate is the place itself, checked against a gazetteer. This is an area, not a spot. The coordinate is its middle, so use it to navigate to the place and not to line up a shot.
Venture keeps every scene location on one map, sorted by how far you'd have to walk. Open it in a new city and it tells you what was shot around you, how to get there, and whether you can actually go in.
