Approximate location — plotted from published sources, not a site visit, and not a guarantee of access.
About 16,900 acres of rugged mountain and coastal scrub rise east of San Diego near the U.S.–Mexico line. Otay Truck Trail and Minnewawa Trail are the main access corridors; vehicles stay on designated roads outside wilderness. Camping is allowed with a 14-day limit under Palm Springs–South Coast Field Office rules.
