Sailboats tack across Lake Pontchartrain off the sandy beach at Fontainebleau State Park on the north shore, with the brick ruins of an old sugar mill standing in the live oaks behind the sand. The Tammany Trace rail-trail runs straight through the park, so the first morning goes to bikes and coffee while the rig stays put. New Orleans is across the lake, and the week settles into slow mornings under the oaks and long days in the city, getting around by streetcar and cab once you're there.
Summer on the Gulf side is hot and humid enough that the hookup is the point of the trip. A rig parked for a week with the air running needs power and a sewer line, and Fontainebleau has both, with 96 premium campsites carrying sewer, water and electric hookups and 23 pull-through sites, reserved online or by phone. Reserve the site before you book the motorhome, because the full-hookup loop is what makes the week work and it's the part that fills.
Mardi Gras and Jazz Fest weeks put the whole region on the same dates. The in-city RV parks, the north-shore loops and the rigs themselves all go to the same crowd, so a festival week means booking the pad and the motorhome together, and early. For a hookup park on the city side of the lake with the French Quarter a cab ride away, the New Orleans RV page covers the stay closer in.
Baton Rouge and the small towns around it, Gonzales and French Settlement among them, are where plenty of Louisiana's listed rigs are parked, which makes Fontainebleau or a New Orleans hookup park the natural first night out of the capital region.
Cajun country and the Atchafalaya from Lake Fausse Pointe
West on I-10, the second leg drops into Cajun country, and the place to settle in is Lake Fausse Pointe State Park on the edge of the Atchafalaya Basin. Campsites sit by coves of the swamp with cypress and Spanish moss hanging over the old borrow-pit canal, and the days go to swamp tours and the towns around Lafayette. The park's 14 premium sites carry sewer, water and electric and its 12 waterfront premium sites have water and electric, so the full-hookup handful is the one to grab first for a week with the air on.
The coast is the next move from there. Palmetto Island State Park keeps 95 premium sites with sewer, water and electric, and Cypremort Point State Park puts the rig on one of 22 premium pull-through sites with full hookups right on the coast. With Lafayette as home base instead, the Lafayette RV page takes Cajun country from town.
Lake Charles and the Creole Nature Trail by day
West of Cajun country the ground flattens into marsh and rice fields, alligators lie out on the banks, and the Creole Nature Trail crosses all of it on the way to the Gulf sand at Holly Beach. In a motorhome the byway is a day out and back from Lake Charles, past the Cameron Prairie refuge visitor center and the Pintail Wildlife Drive, then Peveto Woods and the beach. Visit Lake Charles lists it as an All-American Road with 26 miles of Gulf beaches and warns that services are limited, so fill the tank before you leave.
Sam Houston Jones State Park near Lake Charles is the base, with 30 premium pull-through sites with sewer, water and 50-amp electric. Every night ends back on a full hookup, so the tanks never come into the planning for the byway day. The Holly Beach Crab Festival draws rigs into the Lake Charles area, and if your dates touch it, reserve the base early.
North Toledo Bend State Park, with Kisatchie for a day
Toledo Bend is a big reservoir with flooded cypress along its edges, and the trip in a rig is a weekend or a parked week on the loops at North Toledo Bend State Park. The park lists 8 premium and 55 improved sites, all with water and electric, so arrive with empty tanks and put a full-hookup night at Sam Houston Jones or Lake Fausse Pointe on either side of the stay.
Kisatchie National Forest adds longleaf pine ridges, as a day out or a first-come night. Beaverdam Campground books on recreation.gov and every other Kisatchie site is first come, first served, and the forest lists no RV length or hookups, so a big motorhome is safer there for the day. Two people who want Kisatchie's forest roads, the Toledo Bend shoreline, Caddo Lake or the Creole Nature Trail driven night by night will find those trips in a smaller rig on the Louisiana campervan page.
Farther north, Lake Claiborne State Park west of Monroe has 20 premium sites, 12 of them pull-through, and 67 improved sites with water and electric, the weekend loop for north Louisiana that the Monroe RV page picks up.
