Worth knowing
- Trails is 'most' only because the page allows pets anywhere outdoors; it names no trails (this is an urban park).
- Cats are also welcome outdoors and must be restrained on leashes or in strollers, bags, or backpacks.
- To become a B.A.R.K. Ranger, show the visitor center entrance desk photos or videos of your pet following the B.A.R.K. principles on park grounds; tags are in-person only. A B.A.R.K. Costume Parade was listed for Saturday, October 17 (2026), 10:00 a.m. at the park entrance.
- Pets should never be left unattended anywhere in the park, or in vehicles.
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.
