3 Best Sights in The Southern Black Hills, South Dakota

Legendary former governor and U.S. senator Peter Norbeck personally oversaw the layout of this road, which was designed during the 1930s to complement the park's scenic beauty. The 17-mile route winds around several wooden, pigtail bridges and passes through three rock tunnels that frame Mount Rushmore. Plan an hour or more on this road, because the going is intentionally slow, and you'll want to stop for pictures. The road forms part of the longer Peter Norbeck Scenic Byway.

Like Iron Mountain Road, the construction of Needles Highway was overseen by the late South Dakota politician Peter Norbeck, who took great care to complement the area's natural beauty. The winding, 14-mile road has numerous scenic overlooks, passes through two rock tunnels, and showcases the giant, fingerlike granite formations known as the Needles. The most popular stop on the route is the Needle's Eye, where one of the massive Needles formations sports a hole worn away by erosion. Because the Needle's Eye area is often packed with people and vehicles in tight quarters, use extra caution when passing through or stopping for a look.

People love to scramble around on the big rock formations that line this small, placid, picturesque mountain lake, which is high up in one of the most scenic parts of the park. The lake is very popular among paddlers, and there are kayak and canoe rentals available. Swimmers love the beach, and the campground is always full. A walking path along the shore is great for a relaxing stroll, while several other trails begin near the lake—including the most popular route to Black Elk Peak, the state's highest point. Snacks, drinks, apparel, and other items are available in the general store. All of these things make Sylvan Lake extremely popular, so you might consider getting up early to find parking and beat the crowds.
