As recommended by others, we started the trail from the campsites so it was less to do. The hike is a few hours round trip, hiking is down the whole way and up the whole way back.
This is basically a hike down the watershed of the Chisos Mountains. Every bit of rain in the basin gets drained through this area. It's like a saucer that is tilted to the northeast. All of the creeks were dry, there were some puddles here and there but basically this part of Texas doesn't receive much rain.
There is very little shade at the beginning, you get more shade as you lower into the canyon area. It is quite scenic lower into the canyon area where the creek (now dry) has scoured the rock nice and smooth.
At the end you basically have this sharp dropoff. You can easily just fall because the rocks are slippery so be careful.
Overall a beautiful hike and good introduction to the Chisos Mountains areas but not nearly as good as Santa Elena Canyon. Santa Elena Canyon is an easier hike and gives you much better scenery for your effort.
