I recommend this hike to anyone either staying near the park or passing through on FM 170. It’s a relatively easy 1.5 mile round trip hike into a 200 foot gorge. The trailhead is right off FM 170 and well-marked with little cairns until the canyon appears.
The air is cool and still in the quiet depths of the canyon. It’s quite the change from the windy mountains outside.
I hiked the canyon until I reached an impassable drop off. According to one book I read, the drop off is twenty feet at two stages. You’ll know when you’ve hit it. Without equipment, there is not a method to safely descend.
Also, before that drop, there is a ten foot high pour-off. Don’t feel compelled to make that descent if it looks too difficult. The rocks are really slippery smooth at that point, and the views don’t change much the further in you get.
I wouldn’t go near the canyon during a storm. I can only imagine how the water gets whipping around the narrow canyon. Dangerous!
