Grand Canyon National Park

Grand Canyon National Park is a protected area in northern Arizona encompassing a deep cut carved by the Colorado River through layers of rock. The gorge extends across multiple counties, with two main access points serving the different edges of the chasm.

Theodore Roosevelt declared the area a national monument in 1908 after earlier attempts to protect it had failed. Congress elevated it to national park status in 1919, later expanding the boundaries to include more of the river corridor.

The name comes from the Spanish term for the enormous gorge used by early explorers. Visitors today see traditional settlements and crafts of the Havasupai people, who have lived at the canyon floor for centuries.

The southern edge sits lower and offers lodging and dining year-round, while the northern edge lies higher and is accessible only in summer. Visitors should bring plenty of water and prepare for rapid weather changes within the gorge.

From the canyon floor, temperatures often rise 27°F (15°C) compared to the rim. The rock layers contain fossils of marine animals from when the region lay under oceans.
