Which national park contains the Grand Canyon?

Grand Canyon National Park is the designated protected area that contains the Grand Canyon itself. This park showcases the breathtaking geological wonder carved by the Colorado River over millions of years. Designated as a national park in 1919, it encompasses a vast area of both rims, offering various scenic viewpoints and hiking trails that allow visitors to experience its natural beauty.

The other national parks mentioned are separate entities with their own distinctive features and attractions. Yellowstone is celebrated for its geothermal activity and diverse wildlife, Rocky Mountain is known for its rugged mountain landscapes, and Zion features stunning canyons and rock formations. Each of these parks offers unique experiences, but none contain the Grand Canyon, which is exclusively located within Grand Canyon National Park.
