Your drive on the Badlands Loop Road is almost finished. But your excursion is not. There are plenty of attractions near the two east entrances of the park. First, walk along the quarter mile (round trip) boardwalk at the Fossil Exhibit Trail to learn about the prehistoric animals who lived at the Badlands. Grab a meal and visit the gift shop at Cedar Pass Lodge. The Ben Reifel Visitor Center offers an information desk, a museum, a film, a bookstore and a fascinating Fossil Preparation Lab. And, when you return to I-90, you will find the Minuteman Missile Visitors Center. From 1963 until 1991, this National Historic Site was an intercontinental ballistic missile silo during the Cold War.
