Needles Highway Motorcycle Tour
The Needles Highway (SD-87) is the single most spectacular 14 miles of motorcycle road in South Dakota. Granite spires that look hand-stacked, single-vehicle tunnels carved through stone (the famous Needle's Eye is 8'9" wide), tight switchbacks at the cathedral spires, and Sylvan Lake at the north end. Built in 1922, it was specifically designed to be a scenic drive — modern engineers wouldn't approve, riders love it for that.
The bike for the job
The Needles Highway is the test case for why an adventure bike beats a cruiser in the Black Hills. The 8'9" Needle's Eye tunnel is wider than your bike but the lane through it is single-vehicle — you stop, wait, ride through. The pigtail switchbacks at the cathedral spires are tight enough that big tourers crab through them. The Himalayan eats this terrain.
Routes
Enter Custer State Park from US-16A south of Custer, take SD-87 north (the Needles Highway). Stop at Cathedral Spires Overlook, ride through the Needle's Eye tunnel, exit at Sylvan Lake. Park, walk the lake, photo. Total 1.5h with stops. Pair with the rest of Custer State Park for a half-day.
Better day. Needles Highway south-to-north → Sylvan Lake → SD-89 to the Wildlife Loop (bison, pronghorn, friendly donkeys at the road) → Iron Mountain Road south to north (pigtail bridges + tunnels framing Mount Rushmore) → return through Custer. The full Custer State Park experience.
The full classic. Rapid City → US-16 to Keystone → Iron Mountain Road → Custer State Park Wildlife Loop → Needles Highway → Sylvan Lake → return via Hill City. The Needles is the highlight; everything else makes it a complete day.
Practical info
FAQ
The road itself is 14 miles. Pure riding: 30-45 minutes at the 25 mph speed limit. With stops at Cathedral Spires Overlook and Sylvan Lake (both worth it), plan 1-1.5 hours. Most riders pair it with Iron Mountain Road and the Wildlife Loop for a half-day in Custer State Park.
It's tight but bike-friendly. The tunnel is 8'9" wide and 12'3" tall — your Himalayan is around 35" wide at the bars. The lane is single-vehicle in both directions, so you stop at the entrance, wait if oncoming, then ride through. The approach is the trickiest part: tight, downhill switchback right before. Take it at 10 mph and you'll be fine.
It's challenging but doable for a confident beginner. The road is 25 mph, the curves are tight but not technical, and traffic enforces a slow pace. The single-vehicle tunnels require comfortable low-speed riding. We recommend at least one full season of street riding before tackling it.
Early May through October (weather permitting). The South Dakota Department of Transportation closes SD-87 when snow accumulates. We recommend May to September for the best riding — exactly the season Vintage Rides USA operates.
The Needles Highway is inside Custer State Park, which charges $25 per motorcycle for a 7-day entrance pass. Vintage Rides USA includes the Custer State Park pass with every rental — you don't pay anything extra at the gate.

The Black Hills are why riders come to South Dakota. Granite spires, switchback canyons, pigtail bridges, lakes hidden in pine forests — and roads built for motorcycles. From our Rapid City base, the entire region is in your reach: pick up your Himalayan 450 at 9 AM and you're carving the Needles Highway by 10.
Mount Rushmore is the iconic shot, but the road getting there is the real ride. Iron Mountain Road (US-16A) is the 17-mile masterpiece: pigtail bridges that loop back over themselves, three single-vehicle tunnels each precisely framing the four faces, and tight switchbacks through ponderosa pine. From our Rapid City base it's a 30-minute warm-up to the most photographed ride in the Black Hills.
The Badlands feel like another planet — eroded spires, striped clay, prairie grass disappearing into canyons. SD-240 (the Badlands Loop) is one of the most scenic 39 miles of road in North America, and on a motorcycle it's a different experience entirely. From our Rapid City base, you're at the western park entrance in under an hour.
