The Eglin range is massive and covered with trails but, it's mostly sand. You have to have a Range Pass to be out there, it's $20 for military. The Jackson Guard issues the passes and has the range maps. Other than that, most of the off roading is hidden, out of the way places on private property. I grew up around here and none of my old favorites are open anymore. If you're looking for other, non-Jeep things to do, you'd need an entirely new forum just to cover it all.
