Black Hills National Forest rises out of the Great Plains like an island, a 1.25-million-acre block of granite peaks, ponderosa pine forest, and clear-water lakes that stands alone in a landscape that's otherwise flat to the horizon. From above, the Black Hills look exactly like what the Lakota people called them: Paha Sapa, "hills that are black," the dark pine forest visible for miles across the surrounding prairie. The forest was established in 1897, making it one of the oldest national forests in the country, and it's been shaped by a complicated history: Gold Rush prospectors, Lakota sacred sites, the construction of Mount Rushmore, and a century of timber harvest have all left their marks.
The forest surrounds but does not include many of the most famous tourist destinations in the region. Mount Rushmore is a National Memorial administered by the National Park Service. Crazy Horse Memorial is a private monument. Wind Cave National Park sits to the south. Custer State Park, a South Dakota state park with bison herds, shares a long boundary with the national forest. Understanding those distinctions matters for planning: the national forest is where you go for trails, camping, rock climbing, and mountain biking. The other attractions are separate.
Why Black Hills Stands Out
The elevation matters more than the number. At 7,242 feet, Black Elk Peak (renamed from Harney Peak in 2016, honoring the Lakota holy man) is the highest point in the United States east of the Rocky Mountains. That superlative gives it a view that's disproportionate to its size: on a clear day from the summit stone tower, five states are visible. The experience of standing on a genuine summit, on a maintained trail, in a forest an hour from a mid-sized city, is accessible to a much wider range of hikers than most comparable summit experiences in the Rockies.
The granite spire terrain is the other defining feature. Exposed granite plutons pushed through the limestone surface of the Hills hundreds of millions of years ago, and erosion has sculpted them into the towering needles and spires that make this landscape distinctive. Cathedral Spires, Needles Eye, and the rock formations visible from the Needles Highway are the result of that geology. Rock climbers have been coming to the Black Hills since the 1930s, and the area around Sylvan Lake and Mount Rushmore has established routes that attract climbers from across the region.
The proximity to Mount Rushmore and Crazy Horse Memorial brings millions of tourists to the region, but most of them stay on the main roads. The national forest's trail network sees a fraction of the visitation that nearby monuments attract. Even in peak summer season, trails like Sunday Gulch and Cathedral Spires are far less crowded than you'd expect given the volume of tourists in the region.
Best Trails
Four hundred fifty miles of trails cover terrain from gentle lakeside loops to challenging granite scrambles. Here are four starting points.
Black Elk Peak is the signature hike of the region. The 7-mile out-and-back from Sylvan Lake is the most popular trail in the forest, and for good reason: the summit view from the 1930s stone fire lookout tower is exceptional. The trail is well-signed and maintained, making it a good benchmark hike for gauging fitness before tackling more demanding routes.
Sunday Gulch Trail is the most surprising trail in the Black Hills. This 3.5-mile loop descends into a granite canyon with log ladders, rock scrambles, and walls that close overhead, creating a cathedral-like enclosure unlike any other short trail in the region. It connects to the Sylvan Lake area and is often overlooked by visitors who go straight to the peak trail.
Cathedral Spires Trail is a steep 2-mile out-and-back that climbs past the rock formations visible from the Needles Highway. The trail ends at the base of the spires, with scrambling options for those with experience and the right footwear. It's short but gains nearly 900 feet, making it deceptively demanding.
The Centennial Trail (Iron Creek to Alkali Creek section) offers a different experience: the 111-mile Centennial Trail traverses the entire Black Hills north to south. This 8-mile section near Pactola Reservoir shows the trail at its best, with varied terrain and reservoir views away from the main tourist corridor.
Permits and Passes
Black Hills National Forest is one of the most accessible national forests in the country from a permit standpoint. There is no wilderness permit system (there are no congressionally designated wilderness areas in this forest), no entry fee, and no trailhead quota. Show up and hike.
The primary cost is at Custer State Park, which charges a $20/vehicle day-use fee. Many of the most popular trailheads (Sylvan Lake, Cathedral Spires, Sunday Gulch) are located within or adjacent to Custer State Park. The state park fee is separate from any national forest or federal fee.
Campground reservations through Recreation.gov are strongly recommended from Memorial Day through Labor Day. The main campgrounds, particularly Sheridan Lake, fill weeks in advance for summer weekends. First-come-first-served sites at Whitetail Campground are an option for spontaneous trips but availability is not guaranteed.
The America the Beautiful Interagency Pass ($80/year) covers day-use fees at federal recreation areas. Veterans and those with permanent disabilities may qualify for free passes. The pass does not cover Custer State Park fees, which are administered by South Dakota.
Camping
The Black Hills has a solid network of developed campgrounds administered by the Forest Service, supplemented by Custer State Park campgrounds (separate reservation system).
Sheridan Lake is the largest Forest Service campground in the Black Hills, with 440 sites spread across several loops around a reservoir on the south end of the forest. It's a full-service facility with flush toilets, showers, a boat launch, and a swimming beach. Sites run $18-24 per night depending on hookup type. It books up well in advance for summer. Reservations through Recreation.gov are essential.
Pactola Pines Campground on Pactola Reservoir offers 80 sites with lake access. The reservoir itself is the largest lake in the Black Hills, and the campground feels less crowded than Sheridan Lake despite similar amenities. Open May through September.
Roubaix Lake is the most scenic of the smaller campgrounds, with 56 sites on a small pine-rimmed lake in the northern part of the forest. It's a popular fishing destination and tends to be quieter than the larger campgrounds near Custer. Reservable through Recreation.gov.
Whitetail Campground offers first-come-first-served sites for those who want flexibility. It's smaller (17 sites) and more basic, with vault toilets and no hookups. For dispersed camping options outside developed campgrounds, see our guide on how to get a national forest camping permit.
When to Visit
May through October is the primary season, with peak visitation from late June through August. The core Black Hills summer draws enormous numbers of tourists to the Mount Rushmore and Crazy Horse area, and the Sturgis Motorcycle Rally (second week of August) brings hundreds of thousands of visitors to the region. If you're visiting primarily for hiking, the weeks on either side of the main summer tourist rush (late May to mid-June, and September through early October) offer better trail availability and campground access.
Fall is an excellent time for hiking in the Black Hills. Aspen groves in the higher elevations turn gold in late September, temperatures drop into the comfortable 50s-60s during the day, and trail traffic decreases substantially after Labor Day. Campgrounds remain open through October at most locations.
Winter brings snow to the upper elevations and some trails become snowshoe or ski routes. The forest road system can be icy or closed, particularly on the Needles Highway (typically closed November through April). Snowmobiling is popular on the forest road system from January through March.
Getting There
From Rapid City: This is the primary gateway. Rapid City Regional Airport has direct flights from Denver, Minneapolis, Chicago, and a handful of other hubs. From downtown Rapid City, US-16 southwest leads 25 miles to the Custer area. The Needles Highway (SD-87) runs south from US-16A through the heart of the forest. Budget 45-60 minutes from Rapid City to most main trailheads.
From Mitchell (eastern approach): I-90 west from Mitchell to Rapid City is about 180 miles (roughly 2.5 hours). Continue past Rapid City to the US-16 junction.
From Cheyenne, Wyoming (southern approach): US-85 north from Cheyenne leads through the northern Wyoming Black Hills and into South Dakota near Spearfish. The southern unit of the forest near Hot Springs is accessible via US-385.
Practical Tips
Mountain lions are present in the Black Hills and have been documented near trailheads. The South Dakota Game, Fish and Parks department publishes guidance on mountain lion safety. Review it before backcountry trips, particularly solo hikes or trips with children.
Rattlesnakes occur at lower elevations, particularly in rocky areas and the grassland transition zones near the forest boundary. Stay on trail, watch where you place your hands while scrambling, and keep dogs on leash where the trail passes through rocky openings.
Tick season runs May through August. The Black Hills has both wood ticks and the smaller deer ticks that can carry Lyme disease. Check your clothing and skin after every hike. Long pants and gaiters help in brushy areas. The CDC publishes tick-bite prevention guidance worth reviewing.
The Centennial Trail (111 miles from Bear Butte to Wind Cave National Park) is the multi-day option for serious hikers. The full trail takes most parties 6-8 days. Sections can be done as day hikes or overnight trips. Water is available from streams and lakes throughout the route, but treat all backcountry water before drinking.
Leave No Trace principles apply throughout the forest. The Black Hills gets heavy visitation concentrated in a small area, making responsible practices especially important. For a full review of Leave No Trace principles, see our Leave No Trace guide.
Bears are present but less common than in many western forests. The Black Hills has a small black bear population in the southern units. Bear canisters are not required, but proper food storage and camp hygiene apply. Review bear canister requirements for guidance on food storage practices.
Black Hills National Forest is one of the most approachable national forests in the country for hikers coming from the Midwest and Great Plains. It's not as vast as the western forests, and it doesn't have the permit complexity of the Sierra Nevada or the Pacific Northwest. What it has is accessible, scenic terrain, genuinely interesting geology, and a location that makes it the natural anchor of a trip that also takes in the Badlands, Mount Rushmore, and Custer State Park. Understanding the difference between these various public lands before you arrive makes planning much easier. Our guide on national forests vs. national parks covers those distinctions in detail.
