Which region of the U.S. contains the most national parks?

The Western United States is renowned for having the most national parks due to its diverse and striking landscapes that include mountains, deserts, and forests. Many of the country's most famous national parks, such as Yellowstone, Yosemite, and Grand Canyon, are located in this region. The presence of vast natural areas and unique geological features in the West has led to the establishment of numerous parks aimed at conserving these magnificent environments and making them accessible for recreation and education.

In contrast, the Eastern United States, while home to beautiful national parks like Great Smoky Mountains and Acadia, does not have the same number or size of parks as the Western region. The Southern United States and the Midwestern United States also have national parks, but their total number pales in comparison to those found in the West. The combination of physical geography, biodiversity, and conservation efforts in the Western United States creates an ideal setting for a greater concentration of national parks.
