Road Trip
Overview
South Dakota 87, prominently referred to as the Needles Highway, is a globally renowned scenic driveway carved directly through the dramatic rock formations of the Black Hills. This spectacular roadway winds past towering granite pillars, sharp stone spires, and dense pine forests, creating a dramatic sense of natural scale. Driving this highway requires slow, careful navigation due to its tight curves and iconic narrow tunnels, providing travelers with an intimate, unforgettable encounter with geological artistry.
Practical Info
Suggested Duration1-2.5 hours
Best TimeThis legendary 14-mile segment of SD-87, world-famous as the Needles Highway, is strictly accessible seasonally, typically opening from May through mid-October due to heavy alpine snows. The definitive magic window to drive is early morning between 6:00 AM and 8:30 AM; crisp morning rays flash off the massive unmortared white granite pillars lining the road rails, providing optimal lighting before heavy traffic jams the pass.
Getting ThereThe highway dissects Custer State Park and the Black Hills National Forest. Driving is the exclusive means of transit: the scenic route incorporates multiple single-lane rock-cut tunnels, notably the Needles Eye Tunnel measuring exactly 8 feet 4 inches wide. Due to these strict physical boundaries, all oversized RVs, tour buses, and camper trailers are completely banned from entering the mountain spans.
Travel Tips
- SD-87 (Needles Highway sector) is completely closed and unplowed during winter. From late October until mid-May, heavy steel gates physically barrier vehicle deployment; attempting to bypass these winter structural barricades incurs criminal trespassing charges.
- The alignment of SD-87 features sharp switchbacks with turning radii under 20 feet. Rigs and combinations exceeding a total length of 27 feet are geometrically incapable of clearing these apexes without pinning their frames against granite faces.
- The SD-87 right-of-way cuts through volatile old-growth ponderosa pine ecosystems. Roadside dry-camping or boondocking is illegal across all pullouts; ejecting litigation-grade lighting materials (cigarettes) yields arrest.
Reviews
Positive
- The famous Needles Highway piercing through narrow granite eyelet tunnels delivers unmatched visual impact; the geological wonder lives up to the hype.
- The asphalt surface is perfectly maintained with bold curve signs; iconic spire overlooks feature safe pull-offs, benches, and clean bins.
- Tunnel entrance barriers show clear physical width specs with staff regulating vehicle flows during peak seasons, ensuring orderly and safe transit.
- Buying a通用 vehicle pass grants unlimited cruising on a world-class scenic highway for 7 days, maximizing value and making it well worth the trip.
Heads up
- The famous Needles Eye Tunnel is only 8 feet wide; large SUVs or dually trucks face heavy squeezing, making side-mirror scrapes common.
- Mid-day prime hours face severe congestion; because the narrow tunnel allows only alternating one-way transit, both ends suffer from long idling lines.
- The scenic highway completely lacks gas stations or cafes; visitors will find it highly uncomfortable if they don't pack enough water.
- Belonging to a high-altitude zone, heavy winter snow maps close the highway from October to May, making it completely unavailable for winter tourists.
