Take the path across the creek from Gum Run Parking. Instead of turning left to the Appetizers, continue up over the hillcrest and follow the path to intersect with a gravel road.
THIS IS PRIVATE PROPERTY: BE COOL. DO NOT DRIVE YOUR CAR UP THIS ROAD AND PARK UNLESS YOU OWN PROPERTY IN THE DEVELOPMENT. Be courteous to anyone you encounter here... the access you save may be your own and that of a lot of folks you don't know.
Beyond the road, the trail continues for several hundred more yards, to where the ridge narrows and breaks down into a boulder field. Just beyond the breakdown is the Maze.
p.s. Don't be tempted into thinking that it will be easier to hike out on the road... it is actually a lot steeper and much longer than just taking the trail back.
