Worth knowing
- The phrase 'off roads' is not defined on the page, and the page does not use the word backcountry, so backcountry is left unknown.
- If you plan to hike or take a river trip, someone must stay behind with the pet or you must arrange a kennel service.
- Pets may not be left unattended in vehicles if it creates a danger to the animal or the animal becomes a public nuisance.
How we read the rules
Every statement on this page was taken from the park’s own pets page on nps.gov and the quoted sentences are re-checked against our saved copy of that page each time the site is built. Parks change pet rules for wildlife, heat and trail conditions, and superintendents can close areas at short notice, so treat the park’s pets page and the ranger at the entrance as the final word. Service animals are covered by different rules. Compare all 63 parks.
