Alaska is the largest state in the Western United States—and the entire country—by area, covering over 663,000 square miles.

Alaska is by far the largest state in the Western United States, as well as the entire United States, with an area of 663,300 square miles. This vast state is more than twice the size of Texas, the second-largest state. Known for its stunning wilderness, Alaska is home to towering mountains, sprawling forests, and thousands of miles of coastline. Despite its size, it has a relatively small population, emphasizing its untouched natural beauty. Alaska's major features include Denali (formerly Mount McKinley), the highest peak in North America, and countless glaciers, rivers, and national parks. Its vastness, biodiversity, and resources have earned it the nickname "The Last Frontier."
