Free camping options are limited within the city of New Orleans. However, you can find free or low-cost camping options in nearby areas. One option is the Bayou Segnette State Park, which is about 30 minutes away from the city. While not free, it offers affordable camping options. For free camping, you may need to explore further into Louisiana's national forests, such as Kisatchie National Forest, which offers dispersed camping in designated areas. Remember to practice Leave No Trace principles and be prepared for primitive camping conditions.
