The decision
What this tool is trying to answer
Grand Canyon is not one gate with one status. The South Rim is generally year-round, the North Rim is seasonal, and weather or recovery work can change individual roads and services. The tool separates those access decisions instead of returning a vague park-open label.
- South Entrance Road and Desert View Drive can have different temporary winter-weather status.
- North Rim access is seasonal and can carry additional service or trail restrictions even when paved roads are open.
- Driving between South and North Rim is roughly a 4½-hour trip each way, so checking the right rim before leaving matters.
