Little Big Econ State Forest (Jones East Trailhead)
There are several trails to explore, and while the area might seem small, the trails connect to other areas of the forest. You could walk all the way to the Barr St. trailhead off of SR-426 if you chose. Due west of the trailhead you can find a nice creek. If you walk northwest, you can make it to the Econ River. Below I've attached a map of one of my visits. During this visit, I walked about 3 miles. I walked west to the little creed and explored the area to the south, but I did not walk northwest to the river.
I like this area becaue it's one of the few places in Seminole County where you can find breeding Bachman's Sparrows. However, it's a good place for other pine flatwood species as well, like Common Nighthawk, Pine Warbler, Brown-headed Nuthatch, and Wild Turkey. Near the river or stream, you're likely to hear singing Red-eyed Vireos other birds that enjoy wetter habitats. So far I've found 75 bird species in portion of the forest (between this trailhead and the Barr St. trailhead), but I suspect there's much more to be seen.
