Fees and hours are what NPS lists in its data at the snapshot date. They change: tell readers to confirm on the official park page before a trip. Visits are NPS recreation visits (counted entries, not unique people). Use them only for this park's own months and years, never to rank parks. Campground list and site counts come from NPS and Recreation.gov records. Count fields can differ slightly between the two. The pet rule is the national baseline (36 CFR 2.15). The park may close more areas to pets. Do not claim specific trails allow dogs unless a fact says so.
