There's a new trail out here: the Cedar Chopper Loop. http://www.tpwd.state.tx.us/publications/pwdpubs/media/park_maps/pwd_mp_p4507_140.pdf
Not too challenging or spectacular but it gives you a good loopy way to get down to the Gorman Springs and Gorman Falls trails. I'd never been to see the falls before and both it and the springs were well worth the trek. The spring-fed creek has a ton of water in it but the falls looks like it is not running anywhere near its potential.
