7 popular national parks that restrict dog visitors

Zion National Park, Utah:The number of annual visitors has almost doubled since 2010, with just shy of 5 million visitors in 2025. Dogs, however, remain heavily restricted due to high heat and the presence of harmful cyanobacteria and cyanotoxins in the Virgin River. Still, Zion offers a B.A.R.K. Ranger Program.

Yellowstone National Park, Wyoming, Montana and Idaho:Yellowstone welcomed more than 4.7 million visitors in 2025. While the park allows dogs on paved roads and in developed areas like campgrounds, they’re forbidden from trails due to the extensive wildlife in the area.

Grand Canyon National Park, Arizona:This park draws roughly 4.5 million visitors per year, but if you bring your dog, you won’t be able to explore below the canyon rim.

Yosemite National Park, California:Nearly 4.3 million annual visitors embark on unforgettable outdoor adventures at this national park, but if you bring your pup, you’ll be confined to developed areas only.

Rocky Mountain National Park, Colorado:Around 4.2 million visitors ascended to Rocky Mountain National Park in 2025. As worthwhile as the park is, it’s not a prime destination for pets, as they’re forbidden from all trails, meadows and tundra areas due to wildlife and extreme conditions.

Grand Teton National Park, Wyoming:This Jackson Hole-adjacent gem attracts approximately 3.8 million visitors per year, but pups aren’t among them. Dogs are banned from all trails, pathways, beaches, waterways and public buildings in an effort to protect and preserve the environment and wildlife.
