Why Visit Mickelson Trail Tunnels

The allure of the Mickelson Trail Tunnels lies in their unique blend of history, natural beauty, and accessible adventure. This 109-mile crushed limestone and gravel trail, completed in 1998, features over 100 converted railroad bridges and four distinctive rock tunnels. These tunnels, primarily located in the picturesque section between Hill City and Rochford, and specifically around the Mystic Trailhead, offer a tangible connection to the region's gold rush past and the ingenuity of late 19th-century engineering.

As you traverse the trail, you'll find yourself immersed in the heart of the Black Hills National Forest, surrounded by towering ponderosa pines, rugged canyons, and sweeping meadows. The trail's gentle grades, mostly not exceeding 4 percent, make it accessible for a wide range of abilities, from casual cyclists to avid hikers. Beyond the tunnels themselves, the trail is dotted with 35 interpretive signs, providing fascinating insights into the history of the communities and the railway that once ran here.

Visiting the Mickelson Trail Tunnels is an opportunity to experience the Black Hills at your own pace, whether you're seeking a challenging long-distance ride or a leisurely stroll through a historic landscape. The scenic valleys, majestic views, and diverse wildlife—including deer, elk, coyotes, and wild turkeys—add layers of discovery to every mile.

The Mickelson Trail Tunnels cater to a diverse array of outdoor enthusiasts, making it an ideal destination for various types of travelers:

Getting There & Parking

The George S. Mickelson Trail stretches 109 miles from Edgemont in the south to Deadwood in the north, offering 15 easily accessible trailheads along its route. Each trailhead provides parking, self-sale trail pass stations, vault toilets, and picnic tables.

Trail Passes and Fees (2026)

A trail pass is required for all individuals aged 12 and older to use the Mickelson Trail.

• Daily Pass: $5 per person. These can be purchased at self-sale stations at each trailhead, at the trail office, or from authorized vendors.
• Annual Pass: $20 per person. Annual passes for 2026 are valid through May 23, 2027, and can be purchased online through the Go Outdoors South Dakota site. Note that online purchases may incur a $3 processing fee and require 7-10 days for mail delivery.

It's important to carry your trail pass with you while on the trail. Motorized vehicles are generally not allowed, except for snowmobiles on the Dumont to Deadwood stretch during winter months if snow cover permits.

Key Trailheads for Tunnel Access

While all 15 trailheads offer access, the four historic tunnels are primarily concentrated in the section between Hill City and Rochford, particularly around the Mystic Trailhead (Mile Marker 74.7).

• Mystic Trailhead: This is a highly recommended starting point for those specifically wanting to experience the tunnels. Our team suggests biking north from Mystic towards Dumont or south from Mystic towards Tunnel A to encounter all four tunnels.
• Rochford Trailhead: Another excellent access point, especially if you plan to cycle towards Deadwood or Hill City, as it places you within easy reach of the tunnel sections.
• Deadwood Trailhead: Located at the northern end of the trail, Deadwood is a popular starting point. The 19-mile stretch from Deadwood to Dumont is the longest incline, leading to the highest point on the trail, but it is also one of the most beautiful sections.
• Hill City Trailhead: A central location that provides good access to many scenic parts of the trail, including the tunnels to the north.

Poor to non-existent cell phone coverage can be an issue on certain parts of the trail, so we recommend downloading maps or carrying a physical trail guide. Shuttle services are available from local businesses in towns like Hill City and Rapid City, which can assist with point-to-point trips or bike transport.

Top Things to Do

The Mickelson Trail Tunnels offer a wealth of experiences beyond just cycling through historic passageways. Our team recommends focusing on these top things to do at Mickelson Trail Tunnels to maximize your visit:

• Cycle Through the Historic Tunnels: This is, undoubtedly, the primary draw. The four rock tunnels, particularly those found between Hill City and Rochford near the Mystic Trailhead, are engineering marvels from the late 1800s. They are surprisingly large and provide a cool, dark contrast to the sun-drenched trail. Bring a headlamp or bike light, as it can be quite dark inside!
• Explore the Converted Railroad Bridges: In addition to the tunnels, the trail boasts over 100 converted railroad bridges, or trestles, that offer scenic crossings over creeks and valleys. These bridges are integral to the trail's character and provide fantastic photo opportunities.
• Hike or Run Sections of the Trail: Even if you're not a cyclist, the Mickelson Trail Tunnels hiking trails are excellent for walking or running. Shorter segments around trailheads like Mystic or Rochford allow you to experience the tunnels and bridges on foot. The crushed limestone surface is generally easy to traverse.
• Learn from Interpretive Signs: Along the 109-mile route, 35 interpretive signs share the rich history of the railroad, the gold rush, and the communities of the Black Hills. Taking time to read these signs enhances your understanding and appreciation of the area.
• Wildlife Viewing: The trail winds through the Black Hills National Forest, providing ample opportunities to spot local wildlife such as deer, elk, coyotes, and wild turkeys. Keep an eye out, especially during dawn and dusk.
• Attend the Mickelson Trail Treks: For a guided and supported experience, consider participating in one of the annual Mickelson Trail Treks. The Summer Trail Trek typically occurs in June, and the main Mickelson Trail Trek is held annually the third weekend in September. These events often include shuttle services, meals, snacks, and an annual trail pass. Pre-registration is required.
• Visit Nearby Black Hills Attractions: The trail connects to or is in close proximity to many other iconic South Dakota destinations. Consider extending your trip to include Mount Rushmore National Memorial, Crazy Horse Memorial, Custer State Park, or the historic town of Deadwood Historic District. The Mickelson Trail Tunnels offer a perfect complement to these well-known sites.
• Enjoy the Scenery: From dense forests of spruce and ponderosa pine to open prairie lands, the diverse terrain of the Mickelson Trail offers breathtaking views. The northern sections, especially between Deadwood and Custer, are particularly noted for their beauty, with abundant shade and flowing creeks.

When planning your things to do at Mickelson Trail Tunnels, remember to bring plenty of water, sunscreen, and layers of clothing, as conditions can change. A basic bike repair kit is also advisable.

Best Time to Visit

The Mickelson Trail is open year-round from dawn to dusk, but the best time to visit the Mickelson Trail Tunnels largely depends on your preferred activities and tolerance for weather.

• Spring (April to May): Spring is a beautiful time to ride or hike the trail. The Black Hills come alive with wildflowers and fresh greenery, and the air is filled with birdsongs. Temperatures are generally mild, making for comfortable outdoor activity. However, some water systems and flush toilets at trailheads may still be closed as water is removed during winter months.
• Summer (June to August): Summer is popular for hiking and biking, with lush landscapes and inviting weather. However, summer days can be hot, especially in July and August, so our team recommends riding early in the morning to avoid the peak heat. The "Trolley on the Trail" events, offering accessible rides for those with physical limitations, are held throughout the summer. The Mickelson Summer Trek also takes place in June.
• Fall (September to October): Many consider autumn the ideal time to visit. The Black Hills transform into a mosaic of crimson, orange, and gold as the buffalo grass and aspen trees change color. Cooler temperatures make for very pleasant riding and hiking conditions. The annual Mickelson Trail Trek is held the third weekend in September, drawing hundreds of riders.
• Winter (November to March): In winter, the trail falls silent under a blanket of snow. While water systems are removed from trailheads, making amenities limited, sections of the trail from Dumont to Deadwood are open to snowmobiling if snow cover allows. Other parts are suitable for cross-country skiing and snowshoeing. Be prepared for cold temperatures and potential ice.

For optimal enjoyment of the Mickelson Trail Tunnels and surrounding Black Hills scenery, we recommend late spring or early fall. These seasons offer the best combination of pleasant weather, vibrant natural beauty, and fewer crowds compared to peak summer.
