This trail starts on the Old Ore Road, a long 4WD gravel trail that runs almost the length of the park. It's a great drive that can take all day or all week depending on your mood. In the area of the trailhead the road is at its worse, with numerous potholes that can turn into tire swallowing mud holes if it's been rainy. Once on the trail, though, the going is easy on foot, with the approach to the canyon paved with sorted gravels. The big tinaja is cut vertically into bedrock, and is virtually always filled with water of a turquoise hue, making for a nice contrast against the pinks of the canyon wall and the white of the canyon floor. In early May it was sweltering, but bearable, especially since it's only a short hike if you're just going to the tinaja. The canyon walls have numerous examples of extreme rock deformation, unlike any I have seen. Depending on the season you can have this trail to yourself, although it's more popular than Dog Canyon or Devil's Den.
