Fodor's Expert Review Mickelson Trail

Beginning in Deadwood and running the length of the Black Hills, the Mickelson Trail incorporates more than 100 converted railroad bridges, four tunnels, and 15 trailheads along its 109-mile-long course. Although the grade is seldom steep, parts of the trail are strenuous. A $4 day pass or $15 annual pass are available at self-service stations along the trail, some state park offices, and from the South Dakota Game, Fish & Parks. A portion of the trail is open for snowmobiling in winter.
