Flume Trail (Trail #50)
Trail Quick Facts
Trail Overview
The Flume Trail (officially designated Trail #50) is a National Recreation Trail that winds through the scenic Black Hills of South Dakota, following the historic route of the Rockerville Flumeβan engineering marvel from the 1880s gold mining era. This well-preserved trail takes hikers back in time while offering beautiful views of Sheridan Lake, Spring Creek Canyon, and the surrounding ponderosa pine forests.
Stretching approximately 11 to 13 miles one-way depending on the route taken, the Flume Trail is designated as a National Recreation Trail due to its significant historical importance to the Black Hills region. The trail follows the actual flume bed for much of its length, where hikers can see remnants of the original wooden and stone construction that once carried water 20 miles from Spring Creek to placer gold mining operations near Rockerville. This remarkable water conveyance system operated until 1885 and enabled miners to extract more than $20 million in gold.
Historical Significance
During the Comstock-era gold rush of the 1880s, water was essential for placer mining operations in the Black Hills. Engineers designed and constructed the Rockerville Flume, a combination of wooden box flumes and channels carved into rock, to transport water from Spring Creek (west of present-day Sheridan Lake) eastward to the mining areas near Rockerville. The flume operated for approximately five years before being abandoned in 1885 as mining techniques evolved and operations shifted.
Today, hikers can observe sections of the original flume construction, including hand-carved channels, wooden supports, stone foundations, and two impressive tunnels blasted through solid rock. The trail offers a tangible connection to the Black Hills’ mining heritage and the determination of early settlers.
Difficulty & Trail Character
The Flume Trail is generally rated as easy to moderate. Most of the trail follows the gradual grade of the historic flume bed, making it relatively flat and accessible for hikers of various skill levels. The trail surface is typically 3 to 4 feet wide, though it narrows in some sections and can be rocky underfoot.
Hikers should be aware that portions of the original flume have deteriorated or collapsed over the decades, requiring the trail to bypass these sections with short climbs or detours. While most of the trail presents no technical challenges, some sections feature rocky terrain, narrow passages, and areas where the trail contours along hillsides. The tunnels require caution, and bringing a flashlight or headlamp is strongly recommended for the longer tunnel.
The trail is suitable for families and casual hikers, though the full one-way distance of 11-13 miles may be ambitious for inexperienced hikers. Fortunately, multiple access points and a popular 3-mile loop option allow visitors to experience the trail’s highlights without committing to the full distance.

Both offer a fascinating glimpse into 19th-century engineering.
Spring Creek Canyon: A scenic walk-in fishery with cascading water and picturesque surroundings. Located below Sheridan Lake Dam, this area features interpretive information and excellent photo opportunities.
Historic Flume Remnants: Throughout the trail, hikers encounter sections where the original flume bed is clearly visible, including hand-carved channels, wooden support structures, and stone foundations. Informational signs help interpret these historic features.
Boulder Hill Vista: From the Boulder Hill area, hikers are rewarded with spectacular 360-degree views extending across the eastern Black Hills, the Great Plains, and even the Badlands on clear days.
Sheridan Lake Dam: The trail crosses over or near Sheridan Lake Dam, offering views of this 375-acre reservoir created in 1939. The lake itself submerged the former mining town of Sheridan.
Planning Your Hike
Best Time to Visit
The Flume Trail is officially open year-round, but optimal hiking conditions vary significantly by season:
May through October (Best Season): This is the ideal window for hiking the Flume Trail. Weather is generally pleasant, with temperatures ranging from 50Β°F to 80Β°F during the day. Trail conditions are typically dry and well-maintained. June and July can bring afternoon thunderstorms, so starting early is advisable. Late spring offers wildflower displays, while fall showcases changing aspen colors.
April & November (Shoulder Season): Conditions can be variable. Lower elevations are usually snow-free, but higher sections and shaded areas may retain snow or ice patches. Daytime temperatures range from 40Β°F to 60Β°F. Trail may be muddy in places, especially after snowmelt or rain. These months offer fewer crowds and pleasant hiking if you’re prepared for cooler conditions.
December through March (Winter): The trail remains accessible but presents winter challenges. Snow and ice cover much of the trail, making traction devices necessary. Some sections may be impassable or require winter hiking skills. Temperatures often remain below freezing, and the tunnels can be icy. Winter hiking is possible but recommended only for experienced hikers prepared for winter conditions.
- Late spring (May-June) offers the best wildflower displays and rushing streams from snowmelt
- Summer weekends can be crowded, especially near Sheridan Lake; weekdays offer more solitude
- Early autumn (September-early October) provides comfortable temperatures and fewer insects
- Summer temperatures are moderate in the Black Hills compared to surrounding plains, making this a pleasant escape from heat
Weather Conditions
The Black Hills create their own microclimate, receiving more precipitation than surrounding plains. Weather can change rapidly, particularly in spring and fall.
Summer (June-August): Daytime highs typically 65-80Β°F, with cool nights dropping to 45-55Β°F. Afternoon thunderstorms are common, usually developing between 2-5 PM. These storms can be intense but usually pass quickly. Morning hikes help avoid afternoon weather.
Spring & Fall: Variable conditions with temperatures ranging from 40-70Β°F. Snow is possible at higher elevations into May and as early as October. Wind can be significant. Layers are essential.
Winter: Cold with temperatures often below freezing. Snowfall is common and can accumulate to significant depths. Trails may be icy or snow-covered for extended periods.
Permits, Fees & Regulations
Permits: No permits are required specifically for hiking the Flume Trail. The Black Hills National Forest is generally open for free public access.
Day-Use Fees: Sheridan Lake Recreation Area charges a day-use fee of $5 per vehicle (or $2.50 with Senior/Access Pass). This applies to parking at the Calumet Trailhead and other Sheridan Lake day-use areas. A seasonal pass ($50) is available for frequent visitors. If parking at Sheridan Lake South Shore Campground, notify the attendant that you’re hiking the Flume Trail to avoid being charged camping fees.
Other Trailheads: Coon Hollow, Spring Creek, and Boulder Hill trailheads do not require day-use fees under typical circumstances.
Camping: Backpacking camping is allowed in Black Hills National Forest under Leave No Trace principles. However, campsite selection near the Flume Trail may be limited by terrain and regulations. Developed campgrounds near Sheridan Lake require camping fees ($10-36 per night depending on season and site type).

Trail Etiquette & Conservation
The Flume Trail is a designated National Recreation Trail with significant historical resources. Protecting these irreplaceable artifacts ensures future generations can enjoy this piece of Black Hills heritage.
- Never remove or disturb historic artifacts: Flume remnants, wooden structures, and historic objects must remain in place
- Stay on designated trail: Shortcuts and social trails cause erosion and damage sensitive areas
- Leave No Trace: Pack out all trash, waste, and litter; dispose of human waste properly (200+ feet from trail and water)
- Respect wildlife: Observe from distance, never feed animals, store food properly
- Yield to uphill hikers: Step aside to let ascending hikers pass
- Keep dogs leashed: Required by regulation; prevents wildlife disturbance and trail erosion
- No campfires on or near historic flume structures: Fire damage to these wooden artifacts is irreversible
Hiking Solo vs. Groups
The Flume Trail is suitable for solo hikers and groups alike. While the trail sees moderate use (especially near Sheridan Lake), some sections can be quite remote. Solo hikers should inform someone of their plans, carry adequate supplies, and stay alert. The trail’s popularity means you’re unlikely to be completely alone for extended periods during peak season, but solitude is certainly possible on weekdays and in shoulder seasons.
Groups should be mindful of noise levels and trail etiquette. Large groups (8+ people) should consider splitting into smaller groups to minimize impact and allow other hikers to pass easily on narrow sections.
Safety & Hazards
Wildlife Awareness
The Black Hills support diverse wildlife, including several species that require hikers’ attention and respect.
π» Black Bears (Uncommon but Present):
- Black bears exist in limited numbers in the Black Hills, primarily in central and northern areas
- Sightings are rare but increasing in recent years
- Make noise while hiking to avoid surprising bears
- Store food properly if camping; use bear-proof containers if available
- If you encounter a bear: remain calm, back away slowly, do not run, make yourself appear large

Frequently Asked Questions
Yes, with appropriate route selection. The shorter options, particularly the 2-4 mile out-and-back from Sheridan Lake to the tunnels, are excellent for families. The trail is generally easy with gradual grades. However, parents should supervise children carefully near tunnel sections, areas with drop-offs, and where the trail contours along hillsides. The full 11-13 mile one-way distance may be too ambitious for young children, but the 3-mile loop option or shorter out-and-back hikes are very family-friendly.
Yes, absolutely essential. The first tunnel (from Sheridan Lake) is approximately 100 feet long and completely dark in the middle. Without illumination, you cannot see the trail surface, which may have loose rocks or uneven footing. A headlamp is ideal as it keeps hands free, but any flashlight will work. The second tunnel is shorter and allows more natural light but still benefits from a light source. This is one piece of gear you should not skip.
Yes, dogs are welcome but must be kept on leash. This is a Black Hills National Forest regulation. Leashes protect wildlife, prevent dogs from disturbing other hikers, and keep dogs safe near narrow trail sections and potential hazards. The trail is suitable for fit dogs, though the rocky terrain may be tough on paw pads. Bring water for your dog and pack out all waste. The tunnels can be exciting but potentially overwhelming for some dogs.
Point-to-point hiking requires a vehicle shuttle. Options include: (1) arranging two vehicles (drop one at endpoint, drive to start); (2) having someone drop you off and pick you up; (3) hiring a local shuttle service (inquire at Rapid City outdoor shops or visitor centers). Many hikers solve this by doing out-and-back hikes from a single trailhead instead of point-to-point routes. The most popular approach is parking at Sheridan Lake and hiking out-and-back to see the tunnels.
Mostly no, with one small exception. The Flume Trail (Trail #50) is designated for hiking only and bikes are prohibited on the vast majority of the trail to protect the historic resources and narrow trail sections. The only exception is a short section near Sheridan Lake where Trail #50 shares a segment with Trail #89, which allows bikes. This shared section is less than a mile. For mountain biking in the area, the nearby Centennial Trail and other Black Hills trails offer excellent biking opportunities.
The $5 day-use fee applies to parking at Sheridan Lake recreation areas including the popular Calumet Trailhead. This fee supports maintenance and facilities at Sheridan Lake. The fee can be paid at self-service stations or at the campground entrance. If you have an America the Beautiful Pass (Annual or Senior/Access), you receive a 50% discount ($2.50). A seasonal pass ($50) is available for frequent visitors. Hikers parking at the South Shore Campground should notify the attendant they’re hiking the Flume Trail to avoid camping fees. Other trailheads (Coon Hollow, Spring Creek, Boulder Hill) do not typically require day-use fees.
Natural water sources exist but should not be relied upon without treatment. Spring Creek and several smaller streams cross the trail, but water availability varies seasonally and may be limited or dry in late summer. Sheridan Lake offers water but should be filtered or purified. All natural water sources in the Black Hills may contain Giardia or other pathogens and must be treated before consumption. The safest approach is to carry all the water you need from the trailhead (1-2+ liters depending on route length and weather).
The trail is generally well-marked but requires attention. Trail #50 is marked with numbered signs on trees along the route. However, some sections can be less obvious, particularly where the historic flume has deteriorated and the trail deviates around collapsed areas. Rock cairns mark some sections and bypasses. The trail is popular enough that it’s typically well-worn, but a downloaded map is highly recommended as cell service is unreliable. Some hikers report the trail being “horribly marked” in certain sections, while others find it adequateβyour navigation experience will depend on your comfort level and whether you bring offline maps.
Moderate use with varying crowd levels depending on location and timing. The section near Sheridan Lake, especially the tunnel area, sees the most traffic and can be quite popular on summer weekends. Weekdays and shoulder seasons offer more solitude. Sections farther from Sheridan Lake (toward Coon Hollow or Boulder Hill) generally see fewer hikers. Early morning starts help avoid crowds. The trail is popular with locals and tourists alike due to its proximity to Rapid City and its historical interest, but it’s rarely uncomfortably crowded except potentially on perfect summer weekend days near the lake.
