If coming from the north, take exit 10 from Interstate I15 turning right onto Green Springs Drive and then immediately left onto the West Red Hills Parkway. Drive 1.6 miles and turn right onto Twin Lakes Drive which heads straight north.
If coming from the south, take exit 8 from Interstate I15, turn west onto St George Boulevard. Stay in the right lane and turn right at the first intersection onto N 1000 E. Drive up the hill and turn right at the light onto the Red Hills Parkway. Drive 0.8 miles and turn left onto Twin Lakes Drive which heads straight north.
Keep straight ahead. The Twin Lakes Drive becomes the Old Dump Road and then the Cottonwood Road. At 5 miles from the Red Hills Parkway there is a junction to a turkey farm. Take the left branch. Drive another 1.2 miles to the parking lot for the Yellow Knolls Trail.
The road running north from St George is broken pavement and washboard gravel and is quite rough.
The trail drops down about 100 feet along a gradual slope to the main Yellow Knolls drainage. From here you travel along the wide fairly flat valley between slickrock hills on both sides. The trail then travels gradually uphill on a sand trail rising about 400 feet to the junction of a cross trail, the High Point Trail. From here you can either retrace your route or turn left on the High Point Trail which intersects the main Dump Road and then back along the road to the parking lot.
