NOT ANOTHER “IS IT OPEN?” PAGE
A visit can be possible and still need a different plan.
A road closure, high wind, heat, a current park alert or a missing data layer can all matter without closing an entire park. ParkVisitCheck keeps those signals separate, then explains why the planning friction changed.
Build a briefing →Official park impacts
NPS alerts and events are integrated when the deployment has authenticated access. Otherwise the gap is explicit and the official park link remains visible.
Friction, not false certainty
“Lower / some / higher” reflects only the checked data layers. Incomplete inputs produce an incomplete briefing, never a reassuring green light.
READ THE SIGNALS BETTER

How to Read National Park Alerts Before a Visit
Closure, danger, caution and information alerts do not mean the same thing. Read the category, scope and source before changing a trip.
