The Notch Trail is a 1.5-mile (2.4 km) out-and-back hike located in the South Unit of Badlands National Park in southwestern South Dakota. It features a steep 300-foot (91 m) elevation gain, a 140-step wooden ladder section, and panoramic views of the eroded buttes and prairie grasslands. The trailhead is accessible via Cedar Pass Road, 2.5 miles south of the Cedar Pass Lodge. Per the National Park Service (NPS), the trail is open year-round but subject to closures during high winds (>35 mph), ice accumulation, or flash flood risk. Average hiking time is 65–85 minutes; 72% of visitors complete it between 9:00 a.m. and 2:00 p.m., per 2023 NPS visitor use statistics.
Trail Specifications and Physical Demands
The Notch Trail is classified by the NPS as "strenuous" due to its steep grade, exposed sections, and vertical ladder ascent. The trail begins at an elevation of 2,560 feet (780 m) and climbs to 2,860 feet (872 m) at the notch overlook. The average grade across the first 0.6 miles is 14.2%, peaking at 22.7% on the final 0.2-mile segment before the ladder. The wooden ladder—installed in 2018 by concessionaire Forever Resorts—consists of 140 pressure-treated pine steps with stainless-steel handrails anchored into bedrock. Each step measures 10 inches deep and 4 inches tall, with 1-inch gaps between treads for drainage and debris shedding.
According to the U.S. Geological Survey’s 2022 topographic survey, the trail’s surface consists of 42% compacted gravel, 33% crushed limestone aggregate, 18% native sandstone bedrock, and 7% engineered concrete landings. Traction testing conducted by the NPS in May 2023 using a BOT-3000E digital tribometer recorded a dry-coefficient-of-friction (DCOF) value of 0.71—above the ADA-recommended minimum of 0.60—but dropped to 0.38 when wet, triggering mandatory signage updates at three locations along the route.
Seasonal Accessibility and Weather Constraints
Badlands National Park experiences four distinct seasons, each imposing specific constraints on Notch Trail access. Winter (December–February) sees average highs of 28°F (−2°C) and lows of 8°F (−13°C); the trail remains open unless wind chill falls below −20°F (−29°C) or snowpack exceeds 6 inches (15 cm) depth within 24 hours. In spring (March–May), rapid temperature swings and thunderstorm development create flash flood risk—particularly in the draw just below the notch, where the NWS issues Flash Flood Watches when rainfall exceeds 1.5 inches (3.8 cm) in 3 hours.
Summer (June–August) brings average highs of 88°F (31°C) and frequent heat indices above 100°F (38°C). The NPS mandates that hikers carry a minimum of 1 quart (0.95 L) of water per person per hour—the equivalent of two Smartwater 16.9 oz (500 mL) bottles for the standard 75-minute round trip. Fall (September–November) offers optimal conditions, with low humidity (average 44%), minimal precipitation (1.2 inches/month), and visibility exceeding 15 miles (24 km) on 87% of days, per NOAA’s 2023 Rapid Refresh model data.
Transportation Planning and Multi-Modal Access
Reaching the Notch Trail requires careful coordination of intermodal transit, especially for visitors without private vehicles. The nearest commercial airport is Rapid City Regional Airport (RAP), located 75 miles (121 km) northeast of the park’s South Entrance. From RAP, three primary ground transport options exist: rental car (Hertz, Enterprise, and Avis operate on-site), scheduled shuttle (Badlands Express, operated by Black Hills Stage Lines), and rideshare (limited Uber/Lyft coverage).
Badlands Express runs five daily round trips from Rapid City’s Rushmore Plaza Civic Center (departing at 7:30 a.m., 9:30 a.m., 11:30 a.m., 1:30 p.m., and 3:30 p.m.) with a fixed fare of $32 one-way ($64 round-trip) as of April 2024. Each 22-seat coach is equipped with bicycle racks (capacity: 4 bikes) and luggage compartments sized for two 24-inch roller bags per passenger. The shuttle drops riders at the Cedar Pass Lodge parking lot—the closest publicly accessible point to the Notch Trailhead, located 0.3 miles (480 m) west along Cedar Pass Road.
Private Vehicle Logistics and Parking
For drivers, the Notch Trailhead parking area accommodates 42 vehicles, including six ADA-compliant spaces with 60-inch-wide access aisles. Parking is free and does not require a park pass—though entrance to Badlands National Park itself requires either the $30 America the Beautiful Annual Pass (valid at all federal recreation sites), a $25 7-day park pass, or a $15 one-day pass purchased at the Ben Reifel Visitor Center or via Recreation.gov. As of Q1 2024, 68% of Notch Trail visitors arrived by private vehicle; median dwell time in the lot was 1 hour 12 minutes, with peak occupancy occurring between 10:45 a.m. and 1:15 p.m.
Vehicle dimensions are strictly enforced: trailers over 20 feet (6.1 m) in length and motorhomes exceeding 35 feet (10.7 m) are prohibited on Cedar Pass Road beyond the Cedar Pass Lodge turnoff due to tight switchbacks and limited sight distance. The road has a posted speed limit of 25 mph and features 12 hairpin turns with radii ranging from 38 to 52 feet (11.6–15.8 m), per South Dakota DOT pavement engineering reports.
Safety Protocols and Emergency Response
Two certified Emergency Medical Technicians (EMTs) staff the Cedar Pass Ranger Station during daylight hours (7:00 a.m.–7:00 p.m.), and satellite-linked Garmin inReach Mini 2 devices are deployed at both trail endpoints and the notch overlook. Since 2020, the NPS has recorded 21 medical incidents on the Notch Trail, with the most common being heat exhaustion (38%), ankle sprains (24%), and dehydration (19%). No fatalities have occurred on the trail since its 2005 reconstruction, though 7 incidents required helicopter evacuation—coordinated through Life Flight Network (based in Sioux Falls) with an average response time of 18.3 minutes.
All trail signage complies with MUTCD Standard W13-1 and includes bilingual English/Spanish text. Warning signs at the base of the ladder explicitly state: "This section requires upper-body strength and secure footing. Do not attempt if wearing sandals, flip-flops, or smooth-soled shoes." The NPS tested footwear compliance in summer 2023 and found that 12% of hikers wore non-recommended footwear—primarily Crocs Classic Clog (slip resistance DCOF = 0.29 when damp) and Adidas Cloudfoam Pure (DCOF = 0.33 on wet limestone).
Wildlife Encounters and Mitigation Measures
Black-tailed prairie dogs inhabit colonies within 300 yards (274 m) of the trailhead; bison herds traverse the adjacent Sage Creek Wilderness Area approximately 1.2 miles (1.9 km) east. Per NPS wildlife biologists’ 2023 telemetry data, bison cross Cedar Pass Road an average of 2.4 times per week between June and October—most frequently between 5:15–6:45 a.m. and 7:30–9:00 p.m. Visitors are instructed to maintain a minimum 25-yard (23 m) distance from all wildlife, per 36 CFR §2.2(a). Bison-related incidents accounted for 61% of all wildlife interactions logged in the South Unit last year—none resulted in injury due to consistent enforcement of the 25-yard rule and strategically placed “Bison Crossing” warning signs every 0.4 miles along the road corridor.
Photography, Geology, and Interpretive Value
The Notch Trail traverses the Brule Formation—a 30-million-year-old Oligocene sedimentary layer composed primarily of siltstone, claystone, and volcanic ash bands. At the notch overlook, visitors stand atop a 120-foot-thick (36.6 m) ash deposit originating from the 30 Ma eruption of the ancestral Yellowstone hotspot. Color variations visible in the strata—ranging from pale lavender (illite-rich zones) to burnt orange (hematite-stained horizons)—are enhanced by morning light, making sunrise (5:42 a.m. CST in June) the optimal photography window. Canon EOS R6 Mark II and Sony A7 IV users report best dynamic range results using graduated neutral density filters (Lee Filters 0.6 Soft Grad) and bracketed exposures at f/8, ISO 200, 1/125 sec.
NPS interpretive rangers lead free 45-minute geology talks at the notch overlook twice daily (10:30 a.m. and 2:30 p.m.) from Memorial Day through Labor Day. These programs reference real-time data from the park’s network of 11 soil moisture sensors and 3 automated weather stations—two of which (Sage Creek AWS and Cedar Pass AWS) feed live data to the Badlands NPS website. The Cedar Pass station, installed in 2021, records wind gusts up to 62 mph (100 km/h), relative humidity as low as 11%, and UV index peaks of 10+ during July afternoons.
Visitor Amenities and Concession Services
Cedar Pass Lodge—operated by Forever Resorts under NPS Contract #NAG-18-001—offers lodging, dining, and retail services 0.3 miles from the Notch Trailhead. The lodge’s 2024 menu features locally sourced bison meat from Flying W Ranch (Custer, SD), roasted sweet potatoes from Sodak Produce (Mitchell, SD), and house-made chokecherry syrup from Prairie Berry Winery (Keystone, SD). Wi-Fi is available throughout the lodge’s common areas (download speeds avg. 48 Mbps, upload 12 Mbps), and charging stations compatible with USB-C and Lightning connectors are installed at all 12 lobby seating clusters.
The adjacent Cedar Pass Visitor Center houses interactive exhibits powered by Intel Core i5-1135G7 processors and 27-inch LG UltraFine 5K displays. One exhibit, "Erosion in Real Time," uses lidar-derived 3D models updated quarterly from USGS Earth Explorer datasets to show how gully retreat rates have accelerated from 0.8 inches (2 cm) per year in 1995 to 2.3 inches (5.8 cm) per year in 2023 due to increased precipitation intensity.
Accessibility and Inclusive Design Features
While the Notch Trail itself is not ADA-accessible due to its steep gradient and ladder, the NPS provides inclusive alternatives. The nearby Window Trail (0.25 miles / 400 m loop) is fully compliant with ADA Standards for Accessible Design (2010), featuring a 5% maximum grade, 60-inch-wide asphalt surface, and tactile warning strips at all curb ramps. Audio description guides for both trails are available via the NPS App (version 4.12.1) and include GPS-triggered narration synced to user location within 3 meters accuracy.
A wheelchair-accessible tram service—Badlands Access Transit—operates daily from 9:00 a.m. to 5:00 p.m., departing every 45 minutes from the Cedar Pass Lodge. The 12-passenger electric tram (Proterra ZX5 model) has a 28-inch-wide ramp, priority seating with lap/shoulder belts, and Bluetooth-enabled hearing loop systems. Round-trip fare is $5 per person; reservations are not required but recommended during peak season (June–August) via the Forever Resorts booking portal.
Regulatory Compliance and Permit Requirements
No permit is required for day-use hiking on the Notch Trail. However, commercial filming (including YouTube vlogs with monetization enabled) requires a Special Use Permit issued by the NPS Office of Resource Management, costing $250 plus $75 per production day. Drone operation is prohibited within all Badlands National Park boundaries per 36 CFR §2.17, enforced via FAA-approved geofencing on DJI Mavic 3 and Autel EVO Nano+ platforms. Violators face fines up to $5,000 and/or six months imprisonment under the Federal Aviation Authorization Act.
Pack-in/pack-out regulations apply universally: all food waste, toilet paper, and hygiene products must be carried out. The NPS enforces this through unannounced inspections by Resource Protection Rangers—14 officers trained annually in Leave No Trace Master Educator curriculum. In 2023, 92% of inspected backpacks contained compliant waste containment (e.g., OPSAK odor-proof bags or SealLine Big Line Dry Bags), while 8% were cited for improper disposal of single-use wipes (banned under NPS Policy Memorandum 22-03).

Overnight backcountry camping is not permitted on the Notch Trail or within 0.5 miles (0.8 km) of any developed trailhead. Campers must obtain a free backcountry permit online via Recreation.gov and adhere to strict bear-canister requirements—even though black bears are absent from the Badlands, the NPS mandates BearVault BV500 canisters for all food storage due to coyote and raccoon activity. These canisters weigh 2.2 lbs (1.0 kg) empty and have internal volume of 500 cubic inches (8.2 L), meeting Interagency Grizzly Bear Committee standards despite regional species absence—a policy upheld in the 2022 NPS Backcountry Management Plan Amendment.
Cellular coverage along Cedar Pass Road is provided exclusively by Verizon Wireless (LTE Band 13, 700 MHz), with signal strength averaging −98 dBm at the trailhead—sufficient for voice calls and SMS but insufficient for reliable video streaming. AT&T and T-Mobile users experience near-total outage beyond the lodge parking lot. The NPS recommends downloading offline maps via Gaia GPS (version 12.14) prior to arrival; the Badlands South Unit map layer includes 1:24,000 USGS quad contours, real-time fire danger ratings from the South Dakota Department of Agriculture & Natural Resources, and geotagged photo points curated by the Friends of Badlands nonprofit.
Restroom facilities at the trailhead consist of two vault toilets maintained by Forever Resorts’ sanitation crew on a 72-hour cycle. Each unit includes antimicrobial copper-alloy door handles (99.9% bacterial reduction in 2 hours, per EPA Safer Choice certification), motion-activated LED lighting (12-lumen output), and hand sanitizer dispensers filled with Germstar Advanced 70% ethanol formula. Waste removal occurs via vacuum truck (Kenworth W900L chassis with Vactor 2100 system) every Tuesday and Friday at 5:30 a.m.
The NPS tracks trail usage via infrared counters embedded in the trail surface at 0.2-mile intervals. Data from January–December 2023 shows 127,431 total hiker visits—up 11.2% from 2022—with Saturday accounting for 29% of all traffic and Thursday the lowest at 9%. Peak hourly volume occurred at 11:45 a.m., averaging 18.7 hikers per minute crossing the sensor zone near the ladder base.
Finally, pet policies are strictly enforced: leashed dogs are permitted on the Notch Trail but prohibited on the ladder section and at the overlook due to structural load limits (maximum 250 lbs / 113 kg per step, per 2018 engineering certification). Dog owners must carry proof of rabies vaccination and clean up all waste using biodegradable Wag Bags—distributed free at the Cedar Pass Visitor Center’s front desk alongside trail condition updates printed on 100% post-consumer recycled paper (Domtar EarthChoice 30% PCW).
- Carry at least 1 quart (0.95 L) of water per person per hour on summer hikes.
- Check current trail status via the official NPS app or call (605) 433-5361 before departure.
- Never approach bison closer than 25 yards (23 m); use binoculars or telephoto lenses for observation.
- Download offline maps and emergency contacts prior to cellular blackout zones.
- Secure all food and scented items in approved bear canisters—even in absence of bears.
These practices reflect the NPS’s dual mandate: preserving fragile geological formations while enabling safe, equitable public access. The Notch Trail remains one of the most intensely studied short hikes in the National Park System—not for its length, but for its role as a microcosm of western Great Plains ecology, infrastructure resilience, and adaptive visitor management.
