If you're in the Lafayette/Henderson area in southwest La, consider staying at Cajun Palms RV Resort - awesome place. While in this area, visit Avery Island which is where Tabasco Sauce is manufactured - escellent tour. There are also some swamp tours towards the Miss/La state line near Slidell, La, I believe it's called the Honey Island Swamp Tour or something to that effect. If in the Southeastern part of La along I-12, consider staying at Reunion Lake RV Resort at Robert La - another awesome place.
