The Ponca lived along the lower Niobrara and Ponca Creek until they were removed to Indian Territory in 1877, and Lakota bands hunted the country to the west. The land north of the Niobrara was part of Dakota Territory until 1882, when it was added to Nebraska; the Boyd County part was opened to settlement in 1890, and Boyd County was organized in 1891, named for Governor James E. Boyd.

South of the river, the Fremont, Elkhorn & Missouri Valley Railroad, part of the Chicago & North Western, reached Long Pine in 1881 and Ainsworth in 1882, and the towns along US 20 grew up on it. Brown County was created in 1883 and at first took in present Keya Paha and Rock counties, which became counties of their own in 1884 and 1888. Kinkaid homesteaders filled the Sandhills after 1904. The railroad was abandoned in 1992 and became the Cowboy Trail.

More recent history: in July 2012 the Fairfield Creek fire burned about 117 square miles of the Niobrara valley and nearly wiped out Norden; in March 2019 a flood destroyed the Spencer Dam and damaged the Carns Bridge and river landings; and on August 10, 2026, the state swapped two highway numbers, so US 183 now runs from Bassett north to Springview and NE 7 runs from Ainsworth past Keller Park.

The Niobrara River cuts east across the region in a canyon of pine- and oak-covered bluffs, with spring-fed side streams and waterfalls. North of it, Keya Paha County is rolling tableland between the Niobrara and the Keya Paha River (Dakota for “turtle hill”), and Boyd County runs east to the Missouri River, which forms part of its northeast boundary below Fort Randall Dam. Ponca Creek crosses Boyd County to the Missouri. South of the river, Brown and Rock counties climb from the canyon into the grass-covered dunes, hay meadows and lakes of the Sandhills.

With 6,744 people on about 3,550 square miles in 2020, the region averages fewer than two people per square mile. Keya Paha County had 769 people on 773 square miles.

The Sandhills to the south and west are covered on the Sandhills region page.

The 76-mile Niobrara National Scenic River runs from Borman Bridge near Valentine to the NE 137 bridge north of Newport, through Cherry, Brown, Keya Paha and Rock counties. Float it from the bridges at Norden and Meadville; outfitters do not allow rental boats through Norden Chute, and the NE 137 landing, the last one on the scenic river, was damaged in 2019, so check before you go. Below there the Niobrara forms the south line of Boyd County, then crosses Knox County to the Missouri at Niobrara; its last 20 miles are part of the Missouri National Recreational River.

Waterways

• Niobrara River — canoeing, kayaking and tubing on the scenic river; channel catfish and sauger lower down
• Missouri River — below Fort Randall Dam; Sunshine Bottoms near Lynch is the only access in Boyd County (canoes and kayaks only)
• Keya Paha River — joins the Niobrara in Boyd County
• Ponca Creek — past Anoka and Lynch to the Missouri
• Long Pine Creek — spring-fed trout stream at Long Pine State Recreation Area

Cowboy Trail

The Cowboy Trail, the old railroad line made into a crushed-limestone trail for walking, biking and horseback riding, crosses Brown and Rock counties through Johnstown, Ainsworth, Long Pine, Bassett and Newport. Its best-known spot is the bridge over Long Pine Creek.

Outlaw Trail Scenic Byway

NE 12 is the Outlaw Trail Scenic Byway, 231 miles from Valentine east to Willis near Jackson. In this region it follows the South Dakota line past Norden and through Springview, Burton, Naper, Butte, Spencer, Bristow, Lynch and Monowi, with the Niobrara canyon to the south. The name comes from local stories about horse thieves such as Kid Wade and Doc Middleton, who knew this country in the 1880s; a state historical marker says some called the area “Mob County.” Highway 12 and the Outlaw Trail →

Parks and Camping

• Long Pine and Keller Park in Brown County (trout, camping), and Long Lake State Recreation Area in the Sandhills
• The Nature Conservancy’s Niobrara Valley Preserve, about 56,000 acres along the river with more than 500 bison and hiking trails, open year-round
• Cub Creek Recreation Area, 8 miles west of Springview: free primitive camping and a 27-acre lake
• Camping at the Rock County Fairgrounds in Bassett and the Boyd County Fairgrounds in Spencer
• 9-hole golf at Ainsworth, Bassett and Springview

Most land here is private, so public hunting is on state wildlife management areas and Open Fields and Waters walk-in tracts (check the current Public Access Atlas). Game includes white-tailed and mule deer, wild turkey, sharp-tailed grouse and prairie-chicken in the Sandhills, and waterfowl along the rivers.

• Brown County: Bobcat, Plum Creek Valley, Pine Glen, Keller Park, Long Pine, South Pine and Willow Lake WMAs
• Rock County: Fred Thomas WMA (on the Niobrara north of Bassett) and Nick Lyman WMA
• Keya Paha County: Thomas Creek WMA and Holt Creek WMA
• Boyd County: Hull Lake, Parshall Bridge (check status; closed after the 2019 flood) and Sunshine Bottoms WMAs

Check Nebraska Game and Parks for current regulations and permits.

The Niobrara valley is a meeting place of eastern, northern and western plants and animals, with eastern hardwoods, paper birch and ponderosa pine in the same canyon. Bald eagles winter along the open water of the Niobrara and Missouri. In spring, sharp-tailed grouse and greater prairie-chickens gather on their dancing grounds in the Sandhills grasslands. Bison can be seen at the Niobrara Valley Preserve.

Getting There

US 20 crosses the region east–west; US 183, US 281 and NE 11 run north–south, and NE 12 follows the South Dakota line. Ainsworth Regional Airport handles private aircraft; the nearest airline service is at North Platte, Kearney and Grand Island, Nebraska, and Sioux Falls, South Dakota.

Services

The largest towns are Ainsworth, Bassett and Spencer. Elsewhere services are thin and fuel stops far apart, so plan ahead.

Hospitals

• Brown County Hospital — Ainsworth
• Rock County Hospital — Bassett
• Niobrara Valley Hospital — Lynch

Cattle ranching and haying are the main business, with more crop farming in Boyd County. Towns are small and far apart: Ainsworth, the largest, had 1,616 people in 2020. The region’s population has fallen since its early peaks (Brown County had 6,749 people in 1920), and the towns depend on their main streets, schools and volunteers.
