Magnolia Forest Walk is located near Elmer, LA. The trail is primarily used for hiking.
This looks more like section 4 of the Wild Azalea trail. I have never seen it called the Magnolia walk. It is part of a 31 mile trail and this portion passes through some Virgin forest. Lots of good info here ---- http://www.fs.usda.gov/recarea/kisatchie/null/recarea/?recid=34655&actid=50
This was fairly easy however section 5 is quite a bit more strenuous in places and has more mud and water when it rains.
