Continue to explore Arroyo Tapiado above the mud caves.
At about 1.5 miles there is a right turn onto another arroyo that connects with the Arroyo Seco Del Diablo cut accross road to get to the Diablo Drop-off. It's about 4.5 miles from the mud caves to the end.
Continue up the canyon to the "Dead End" fork. Turn left and continue up the creek. Narrow in spots. There is a campsite at the end.
