The Grandstaff Hiking Trail (formerly known as the Negro Bill Hiking Trail) features a perennial stream in its scenic canyon. Morning Glory Natural Bridge, which has a span of 243 feet, is the sixth longest natural rock span in the United States.
Hiking and running only.
From the parking area next to Utah 128, follow the trail up the left side of the stream. Keep going upstream for about 1.5 miles.
Morning Glory Natural Bridge is located at the end of the second side canyon on the right. The trail forks just below this canyon. Follow the trail to the right, cross the stream and ascend a steep slope. Morning Glory Bridge is located at the end of the trail about 0.5 miles up the canyon from the stream.
Flora & Fauna
Do NOT touch the poison ivy that grows below the pool under the bridge! Poison ivy plants have dark green, shiny leaves with serrated edges in clusters of three.
