Start at the parking lot and follow the dirt road for a very short bit, then cross to the shoulder of Old Canyon Road. Continue along this road for less than a tenth of a mile and merge to the trail on the right. Follow this trail as it curves with the road and then heads down towards the falls. The trail will follow along the rocks and continue down towards the falls.
Avoid the road and houses by staying to the west of them until you see the dirt road turn south, away from the paved road and follow that to a quick left staying on the shoulder. Cross the road at its apex and drop just above the falls. Take a few pictures, enjoy yourself, and then turn around and head back the way you came!
