Fun singletrack that's technical enough to keep it interesting (watch out for the roots!)
Take I 45 to exit 15 (by the Gulf Greyhound Park). Take the road just South of the greyhound park to the West. Just a couple of miles down the road on the right hand side is the park entrance. Go to the T in the road and take a left to the parking lot. The entrance and the trails are marked with arrows.
