The Longest Tunnel In South Dakota Has A Truly Fascinating Backstory
South Dakota has some of the most unique and must-visit tunnels in the country, thanks – in part – to such innovative passages as the Needles Eye, Hood, and Scovel Johnson Tunnels. In addition to these more one-of-a-kind channels, South Dakota is also home to more traditional structures, like the one along the George S. Mickelson Trail:
Located in the Black Hills, the George S. Mickelson Trail is a 109-mile-long stretch that follows the same route as an old railroad branch line constructed by the Chicago, Burlington, and Quincy Railroad.
Named for the late Governor George S. Mickelson, the Trail was completed in 1998 and features a whopping 15 different trailheads, making it one of the most popular paths in the Mount Rushmore State!
Beginning in Deadwood and ending near Edgemont, the George S. Mickelson Trail is a must-see for not only the surrounding Black Hills beauty but for its 100 converted railroad bridges and 4 rock tunnels, one of which spans 40 feet.
Situated just south of Mystic, the long and famous tunnel was the result of blasted rock and walls lined with specially-made beams that fit its curves and give it its distinct keyhole appearance.
Whether you walk, jog, sprint, or ride your bike, you are guaranteed an unforgettable experience along the George S. Mickelson Trail!
In addition to its tunnels, the Trail connects several of South Dakota's favorite towns and attractions to one another, including Custer, Hill City, Lead, and more.
As if you needed a reason to visit, the George S. Mickelson Trail is also the setting for several special events, which can be found on the South Dakota Game, Fish, and Parks'
The George S. Mickelson Trail is open year-round from dawn to dusk, with showers, flush toilets, and other water systems open from May 1st through September 30th.
