trip advice: Cima Road (at the basin of that straight stretch of I-15 just after you come off of Halloran Summit). Continue on through the Mojave Preserve (for undisturbed patches of Joshua Trees) Con through the old train depot in Kelso. Proceed a little farther south on Kelbaker Road to the Kelso Dunes and Granite Mountains. Cross I-40 and go right on 62. Take the north entrance into JT. Get on El Dorado Road and then Cottonwood Springs Road, for a scenic drive. Cottonwood runs into I-10.
