The Floor of the Valley Road, also known as the Zion Canyon Scenic Drive, follows the canyon of the North Fork of the Virgin River, also known as Zion Canyon, through Zion National Park, Utah. A precursor to the present nine-mile road was first built in 1916, but was later redesigned by the National Park Service Branch of Plans and Designs to highlight the natural features of the valley while presenting a natural-appearing built environment. The road begins at the south boundary of the park and ends at the Temple of Sinawava.
