Dogs at Zion

The short list

The NPS pets page, updated September 14, 2026 and re-read October 3, 2026, says properly restrained pets are welcome along public roads and parking areas, in developed campgrounds and picnic areas, and on the grounds of Zion Lodge. The only trail that allows pets is the Pa’rus Trail, which begins at the Zion Canyon Visitor Center. Pets are not permitted on any other trails, in wilderness areas, on shuttle buses, or in public buildings.

That is not a hiking permit for the canyon. Do not take a dog up a trail that is not Pa’rus. Do not put a dog on the shuttle and sort it out at the top.

Leash

Pets must be restrained on a leash no longer than 6 feet. Retractable leashes that extend further than 6 feet are not allowed. A fixed 6-foot leash matches that sentence. A reel that can run longer does not.

Pet owners remove waste from campgrounds, picnic areas, parking lots, roads, pet-friendly trails, and other developed areas. Keep the dog’s noise reasonable. Pets can harass wildlife by making noise or scaring animals off.

The river is not for dogs

The same page says Zion monitors the Virgin River for harmful cyanobacteria and cyanotoxins, which may be present at any time of year. Keep dogs out of the water and on a leash. Dogs may ingest cyanobacteria or untreated water and be exposed to cyanotoxins. Check the park site for current cyanobacteria information: nps.gov/zion pets. This page is not veterinary advice and does not describe symptoms or treatment.

Heat and a parked car

The page says Zion is hot, and that during most of the year a vehicle interior can quickly warm to dangerous levels. Leaving a pet unattended in a vehicle when conditions pose a health risk is prohibited. Properly restrained pets may be left unattended in developed campgrounds only when conditions are safe and the animal is not making unreasonable noise, such as barking or whining. The page says to be aware of the extreme environment before you bring a pet, and that summer can be especially challenging. It does not give a pavement temperature.

If the day you planned is a trail the pet cannot use, the page suggests leaving the animal at home or with a local boarding kennel. It says veterinarian services are in Hurricane, St. George, Kanab, and Cedar City, and that boarding kennels are in those towns and in Rockville. That is the park’s town list, not a clinic recommendation from this site.

Service animals, defined on the page as dogs individually trained to do work or perform tasks for a person with a disability, may accompany their owner to all park locations. Dogs whose only role is comfort or emotional support do not qualify as service animals under the definition the page uses.

Snow Canyon allows more trail

Snow Canyon State Park is the closer place if the point of the day is walking a leashed dog on mapped trails and staying in the campground. Its know-before-you-go page says leashes are max 6 feet (the B.A.R.K. section says under 6 feet) and that the trails are dog friendly if you stay on the mapped ones. Read that on snowcanyontours.com/dogs.html. This Zion page is dogs.html, also at zioncanyontours.com/dogs.html.

A small kit

Some links on this page earn us a commission at no extra cost to you.

Bring a fixed leash that stays at 6 feet, waste bags, and booties if the ground is hot. The pets page does not require booties. Prices were on the product page on October 3, 2026. Links go straight to the retailer.

Riding a bike on Pa’rus is a different set of rules: e-bikes.
