The park is named for a nearby spring. The water from Big Spring forms the scenic Shermans Creek. Approximately 100 tables and five shelters are located in the park. Picnic shelters are available for reservation.
Historic interpretation is provided at the trailhead.
The park provides access to the Iron Horse Trail which is designed for both day hikes and overnight hiking. While no camping is permitted in Big Spring State Park, public camping is permitted at the nearby Fowlers Hollow State Park from the second Friday in April until the end of the antlerless deer season in late December. Prior to this, extensive logging occurred. The woods were cut to supply tanneries, barrel manufacturers and charcoal furnaces. A tannery near the spring operated from early in the 1800s until 1860.
