I don't think there is a Point Washington State Forest trail per se, but there are 2 trails that I rode while on vacation in South Walton area that snake through the forest. The first is Longleaf Greenway trail which is an out and back that connects to Eastern Lake Trail, which is inside a state park and requires a $2.00 admission fee. Both trails feature similar terrain: flat, covered with pine needles, occasionally sandy and rooty. Of the two, Longleaf seemed a little twistier and funner, but I recall getting lost along the trail somewhere because of the numerous intersections with nature/hiking trails. Eastern Lake Trail was well marked and has 3 loops of varying lengths. Here's a really nice map to see where the trails are if you are vacationing in the area and want to get your ride on: http://www.waltonoutdoors.com/wp-content/uploads/2012/02/PointWashTrail.pdf
I also rode on a 29er hardtail and did have to walk some of the sandier parts, but definitely doable without a fat bike.
