“This short route leads through varied Arizona terrain, past a waterfall to the park boundary.”— Mike Barcom
Ernie's Falls Trail travels north to the signage at the boundary line. It is level at first and then descends into a wash. The waterfall is located off to the right at a rock outcropping as you descend. Look for saguaros close to the spot. You can go beyond the falls area to the wash, there is the National Park boundary line and a gate.
Feel free to pass through the gate, as it denotes the National Park/National Forest boundary, just make sure to close the gate behind you. Another .1 m down into the wash (seasonal water but can be flowing and full at times), there are slick rock boulders to sit on that make a great place to rest and eat a snack before returning back to the trailhead. The rest area described is actually in the National Forest, but journeying out to this point is pleasant and well worthwhile.
