Approximate location — plotted from published sources, not a site visit, and not a guarantee of access.
Trilobite Wilderness lies south of Interstate 40 in the Mojave Desert, accessed from Kelbaker Road and BLM routes toward the Needles–Ludlow corridor. The desert mountains hold Paleozoic sedimentary rocks that give the unit its name. There are no developed trails or water sources.
Cultural sites and artifacts are protected by federal law (ARPA/NHPA) — stay on established routes, touch and remove nothing, and follow the managing agency's and the affiliated tribe's guidance on access.
