Campgrounds and RV parks near Arnold Line, MS

Water recreation drives most trips. Little Black Creek Campground and Park surrounds a 640-acre lake and offers camping, fishing, swimming, walking, bike riding, kayaking, and picnicking, and Paul B Johnson State Park adds a swimming beach, splash pad, disc golf course, and multiple fishing piers on Geiger Lake. Hattiesburg/Okatoma KOA Holiday sits near the Okatoma River, a popular canoe and kayak run, and is close to the Longleaf Trace, a 44-mile paved rail-trail running from Hattiesburg to Prentiss. Families also use Shady Cove RV Park and Four Season's RV Park as bases for downtown Hattiesburg attractions. History travelers can visit the Mississippi Armed Forces Museum at Camp Shelby, an easy day trip from any campground in the area.

The area has a humid subtropical climate, so campgrounds operate year-round, but conditions vary sharply by season. Spring and fall are the most comfortable windows for RV travel, with mild days, cooler nights, and manageable humidity. Rainfall is abundant and spread fairly evenly throughout the year, though winter is typically the wettest season and fall the driest. Summers are hot and sticky, with afternoon thunderstorms common. Atlantic hurricane season runs from June through November, with peak activity in August and September, and inland tracks from the Gulf can bring heavy rain and wind to the Pine Belt. Travelers watching a named storm should monitor National Hurricane Center advisories and confirm park status before arrival. Winters are short and mild. Freezing nights occur but are usually brief, so heavy winterization is rarely necessary. Weekend demand at Paul B Johnson State Park and Little Black Creek Campground and Park peaks from spring break through Labor Day and again during University of Southern Mississippi home football weekends.

Sites in the Pine Belt sit under tall longleaf and loblolly pines, so shade is plentiful but satellite reception can be spotty. Terrain is gently rolling. Paul B Johnson's campground spreads across rolling ground with both older numbered sites and newer sites featuring paved pads and more level ground, and lakefront spots offer direct water access, though utility connections can be spread out. Commercial parks in the area tend to offer full hookups, laundry, and pools. The KOA property includes fishing lakes, a swimming pool, and pull-through sites suitable for larger rigs. Cell service is generally reliable near Hattiesburg and weaker deeper into the national forest. Expect mosquitoes and biting flies from late spring through early fall. Pets are welcome at most parks on a leash, but pets are not allowed in cabins or state buildings at Paul B Johnson.
