Approximate location — plotted from published sources, not a site visit, and not a guarantee of access.
BLM wilderness (~26,000+ acres) protecting the tall, vehicle-free northern Algodones / Imperial Sand Dunes north of State Route 78. Hiking and horseback only — the quiet counterpart to the Gecko Road OHV playground already in the atlas south of the highway. Tallest dunes rise in the central wilderness core.
