The Appalachian Mountains are a major mountain range in eastern North America, stretching over 1,500 miles from Georgia in the south to Maine in the north. They are known for their rolling hills, deep valleys, and diverse ecosystems, which include forests, rivers, and wildlife. This mountain range is one of the oldest in the world, formed over 480 million years ago. The Appalachians are home to several national parks, including Great Smoky Mountains National Park, which attracts millions of visitors each year for hiking, camping, and enjoying the natural beauty of the region.
