The National Park Service designates certain days of the year where visitors are allowed to tour the National Parks free of charge. By visiting http://www.nps.gov/, tourists can view a list of National Parks across the country and each park will have dates of fee free weekends if they offer them. Most of the dates coincide with holidays throughout the year. In South Dakota, Bad Lands National Park offers nine days throughout 2014 that are free for people to explore. So why should Badlands National Park be on someone’s list of things to do on one of these weekends? Bad Lands National Park contains over 64,000 acres of prairie wilderness, which is the largest in the country. Although it is free to visit during these times, other fees such as camping fees may still be in affect. Bad Lands National Park is located 75 miles east of Rapid City, SD and easily accessed by I-90.
