This is an officially designated off-road area that has a number of parts. The dry lakebed itself is most popular with visitors, if not always off-roaders. Still, it's flat clay, hard and smooth, and a prime racing surface for all kinds of vehicles, even landsailers. Model rocket and remote control plane enthusiasts love the bed and private planes sometimes land here.
The real favorite spot for off-roaders is the basin, between the lake and the ragged jut of the Shadow Mountains. The terrain is kept varied by the dry washes that cross it, but it's an easy ride - if the creosote bushes let you see where you're going. Races are scheduled here frequently.
The Shadow Mountains are a different kind of off-roading experience altogether. This rough and rugged area is pocked with mine shafts, which means caution when riding is necessary.
The last part of El Mirage is Twin Hills which is, indeed, hilly. It's also largely deserted, so if you want a little more of a secluded experience, this is a good choice.
This is an area, rather than a trail, and length of ride varies mostly by how long you'd like to.
