Some of the guys in our Boy Scout Troop, Troop 118 out of La Vernia, Texas, hiked this trail. We uploaded some pictures here in our photo album:
Now, before you go on this trail, plan on a mandatory 30 minute orientation at the Barton Warnock Education center in Lajitas. This is new, but they won't issue you a hiking or back-country camping permit until you do it. They are planning to have it on DVD slideshow in the near future, but for right now, they have the slides printed in a binder that you must read. And the center doesn't open until 8am, so if you want to get an early start on the trail I would suggest that you do the orientation, pay for your back-country camping and get your permit the day before you actually want to hike. Otherwise, you get a late start.
We started at the East trailhead, and looped around to the West trailhead. We left at 10am on a Tuesday (after orientaton at Barton Warnock Education Center), and finished the trail at 4pm on Thursday. This was with 2 adults in their 40's and 3 youth ages 15-16.
Fortunaely for us the springs at Reza homestead and Rancherias were active and we didn't have to trek in an additional 24 pounds of water in addition to how heavy our packs were (50-60 lbs.)
There was a part of the trail that had been washed out and our footing was no more than 4 inches wide, (a literal foot's width, which we reported to the TPWD), but other than that the trail was awesome. The first day's hike was the day that was the most difficult, mainly because of the line of ascent. I think we went up a good 1500 feet in a mile or so.
We all had a great time, and enjoyed the hike immensely. The views were spectacular, sunsets and sunrises gorgeous. Our only regret was that we didn't see more wildlife along the trail. Saw plenty of evidence, scat, etc. - but not very much living breathing animals.
