Needles Highway Scenic Drive follows SR 87. The 14-mile route through Custer State Park threads among the oddly shaped, weathered granite spires from which the highway derives its name. One of the more prominent formations along the way is the Needle's Eye, which stands in excess of 30 feet and has a slit down its center about three feet wide. Drivers will encounter several hairpin curves and narrow tunnels along the route. The tunnel dimensions are 12 feet by 8 feet, 4 inches and 12 feet, 3 inches by 9 feet. The highway culminates at Sylvan Lake.
Note: Due to the narrowness of the route, those with large trailers or motor homes should use extreme caution or avoid this road.
