On land, the Sumter National Forest offers hiking and gravel forest roads within a short drive.

Spring and fall are the most comfortable seasons for RV travel around Joanna. From March through May, daytime highs move from the 60s into the 80s Fahrenheit, wildflowers bloom in the Sumter National Forest, and lake water begins to warm. Fall brings drier air, cooler nights, and reliable color in the hardwoods through October and into November. Summer is the peak booking window. June through August is hot and humid, with afternoon thunderstorms common and highs frequently in the upper 80s to low 90s. Lake Greenwood State Park sites at premium lakefront loops can book up to 13 months ahead for summer weekends and holidays, and a 14-night maximum stay applies between April 1 and August 31. Winter is mild by northern standards but wet, with cold snaps and occasional freezing rain. Most nearby campgrounds stay open year round, and the Lake Greenwood State Park campground operates through the winter. Some Croft State Park camping and equestrian sites are scheduled for rotating closures during the winter 2026 to 2027 season for remediation work.

Sites at Lake Greenwood State Park have paved pads with picnic tables and fire rings, and all 125 sites offer 50-amp electric plus water hookups, with a dump station on site. There are no individual sewer hookups at the state parks in this area, so plan tank capacity accordingly. Big rigs up to about 40 feet fit at many loops, but interior turns can be tight.

The office campground offers 20/30-amp service and the lakeside campground offers 20/30/50-amp, with a centrally located dump station. Firewood should be sourced locally to help prevent the spread of forest pests. Pets are allowed in most outdoor areas on a leash no longer than six feet.
