Andrew Jackson State Park in Lancaster, South Carolina features a multitude of things to do including a museum area, hiking trails, a lake, a campground, and an outdoor amphitheater. The museum is open on Sat-Sun from 1-5:00 p.m. and admission is $2.00 for adults and free for those under 15. For campground reservations, go here. The building that houses the museum also has a gift shop and store with historical items. There is a large parking lot that can accommodate RVs if you are just there for the day and not camping.
There is one hiking trail loop of 1.1 miles that goes past the historical buildings, monuments, and Andrew Jackson statue and then leads you through woods of oak and pine. The second trail follows the lake for 1.0 mile also in a loop and my two dogs and I were able to take the whole trail with no problems.
I really enjoyed exploring the grounds and walked around the historical buildings several times during the week we were camping. In addition to the museum building, there is a schoolhouse, a meeting room building, and a historical garden. There are special events throughout the year and a large picnic shelter area that can be reserved.
