Thing to Do
Saddle Rock Trail Geology Hiking Tour
Participants may also start their tour at the Lower Saddle Rock Trailhead and hike up and down the trail for a 3.2 mile round-trip hike. Another option is to take the Summit Shuttle to the Summit of Scotts Bluff when it is available.
This is a 1.6 mile (one-way) hike along the Saddle Rock Trail. The self-guided tour is set up to begin at the summit of Scotts Bluff. However, you can also begin at the lower trailhead which is located just east of the visitor center. There is an elevation change of 435 feet on this trail and no water is available along the trail. To get to the first stop, drive to the summit of Scotts Bluff and take the North Overlook Trail to the northmost overlook. There you will see a view that reaches across the North Platte River Valley.
