Grand Canyon Dog Policy
Grand Canyon National Park is Somewhat Dog Friendly
The Grand Canyon offers some of the most impressive natural landscapes in the world. The canyon was cut by the Colorado River, and stands an impressive 277 miles long, and up to 1 mile deep and 15 miles wide at its largest extents. The canyon was formed over the course of millions of years, and visitors can marvel at the many colored layers along the canyon walls that represent different geologic periods. There are trails that descend into the canyon and travel over and across the river far below, though dogs are not allowed on these impressive trails.
Grand Canyon National Park is a fairly dog friendly park, particularly the side on the South Rim. Dogs are allowed in campgrounds, and on trails that are above the rim. There is also a kennel at the South Rim that can be used if you want to take the longer hikes/etc.
You can find more information about the kennel here: Grand Canyon Kennel at the South Rim
Dogs are permitted on trails above the rim of the canyon while on 6' leashes.
On the North Rim side, dogs are only allowed on the bridle trail.
On the South Rim, there are several miles of trails where dogs are allowed that are above the rim.
Dogs are not permitted on any trails below the rim of the canyon.
