Scotts Bluff National Monument

The sandstone and clay bluffs rise roughly 800 feet above the North Platte River valley, making them visible from a long way out across the flat Nebraska panhandle — the same quality that made the formation a critical navigation landmark for emigrants on the Oregon, California, and Mormon Trails. That history is still present here: the monument preserves actual trail remnants, and the visitor center holds what the National Park Service describes as the world's largest collection of William Henry Jackson's artworks.

The Summit Road is the draw for riders. Built in the 1930s by the Civilian Conservation Corps, it is the oldest concrete road in the state of Nebraska and the only road in the state that passes through automobile tunnels — three of them. The 1.6-mile climb threads those tunnels to a summit parking area, where two short paved trails lead to overlooks. On a clear day the view stretches east toward Chimney Rock. One practical note before you ride up: the road has a height limit of 11 feet 7 inches and a length limit of 25 feet, and trailers are not permitted. Rockfall and high winds can close it without much notice, so it's worth a quick call to the visitor center if conditions look uncertain.

The monument is operated by the National Park Service and sits just west of Gering off Nebraska Route 92. Entrance fees apply. Summit Road hours vary by season, and the road can close for rockfall or weather at any time of year, so build a little flex into your day if this is a planned stop.
