Recreational Opportunities

Visitors can explore the many trails crisscrossing Jefferson Barracks Park and watch the barges as they make their way up and down the river. The historic Notre Dame Motherhouse and Notre Dame High School are just up the hill behind the paved trail, and visitors can also take advantage of striking views of the bluffs on the Illinois side of the river.

Historical buildings and a museum are all part of the historical theme of the park. Jefferson Barracks, a U.S. Army Post that dates back to 1826, is home to WWII and Civil War re-enactments every year. Scenic views of the Mississippi River can be found at the Powder Museum and the Scenic Overlook. The fencing around the Scenic Overlook was constructed out of Civil War gun barrels.

An amphitheater is located in the historic section of the park and includes a 31-foot by 26-foot stage overlooking a grass seating area that will accommodate up to 5,000 people. Those visiting Jefferson Barracks Park can also grill, play disc golf, use the archery range or access the Pavilion at Lemay, a state-of-the-art recreation facility that features a gym, outdoor pool, indoor track and fitness classes.
