It's only after school starts and summer's minivan caravan ends that South Dakota's Black Hills roll out some of their finest weeks. Days dawn frosty, then warm into a palette of sharp blue skies and patches of glowing aspens and cottonwoods sprinkled among prairies and pine forests.
Click ahead for a look at some of our top fall stops in the Black Hills, including the views from the Needles Highway in Custer State Park (pictured).
Custer State Park's annual Buffalo Roundup (late September) draws thousands of visitors eager to experience the Wild West scene. The park's bison herd, 1,300 strong, cascades over the hills toward corrals. As cowboy whips tear at the clear autumn air, a rumbling that's equal parts sound and seismic event rolls up through the shoes of everyone straining for a view at the wooden fence. gfp.sd.gov 
After cowboys doctor the bison and sort a few out for sale, the gates swing open, releasing the herd back into Custer's 71,000 acres. But even with fall's star event over, the Black Hills leave plenty to see.
The 109-mile Mickelson Trail runs the length of the Hills, putting epic views in reach for casual bikers. The crushed-stone path follows old railbeds; trestle bridges, rock tunnels and gentle grades are generously spread between 15 trailheads, so that even as you're savoring one of the prettiest rides of your life, you're never far from lunch and a rest in towns like Custer, Hill City, Lead and Deadwood.

Spearfish Canyon draws sightseers to the Hills' northern edge, where limestone walls rise like hanging gardens decorated with aspens, birches, oaks and cottonwoods. It's enough to charm even those who have seen their share of grandeur, including John Muir, Teddy Roosevelt and Frank Lloyd Wright.
For unrivaled scenery, take the Spearfish Canyon Scenic Byway, 20 miles of meandering creek beds, craggy cliffs, plunging waterfalls and serene forest. At the bottom of the canyon, Spearfish Creek pours over and around the rocks, gurgling at the feet of fishermen placing trout flies in quiet eddies with a delicate touch transmitted through 20 yards of monofilament line.
This classic tourist train whistles and chugs between Hill City and Keystone for a rare chance to ride behind a vintage steam engine. The tracks thread up Tin Mill Hill, through pines and rocks, past a distant view of Harney Peak and past free-roaming cattle and the occasional deer and antelope. Seasonal excursions on the 1880 Train include a Wine Express and Oktoberfest Express.

Wildlife and scenic drives fill Custer State Park's 71,000 acres; don't miss the narrow, 14-mile Needles Highway that winds around and through the park's magnificent granite spires. The rustic State Game Lodge (pictured) has remodeled its dining room, offering a scenic spot for meals.

Sure, you've seen it in a million pictures. But Mount Rushmore is still inspiring when you actually visit. Enjoy the view, the movie explaining why these presidents are included and the visitors center that details the process of creating the monument. Mount Rushmore's evening lighting ceremony runs daily until September 30, then the sculpture is lit for one hour each fall evening.
The project aims to be the world's largest sculpture. Ruth Ziolkowski (wife of the late Korczak, who in 1948 began carving the image of Crazy Horse astride a horse) and seven of their 10 children continue the work on the massive Crazy Horse Memorial, not accepting any government money to do so. A spacious visitors center tells the story of the carving with a short film and celebrates Native American life and culture with exhibits and displays.
