Lone Star Hiking Trail
Did you know that Texas has it's very own "Appalachian" Trail? Okay, well, it's really not anything like the Appalachian Trail. No mountains, but hey, that can be a good thing. Especially in the hot, humid summers.
The Lone Star Trail is about 129 miles long and wanders through the Sam Houston National Forest. It's mostly flat with some wet areas. Bridges are in place for easy creek crossings. For more information:
