Picacho Peak Wilderness is a protected desert area in southeastern California near the Arizona state line, covering nearly 9,000 acres around Picacho Peak. Managed by the Bureau of Land Management, it preserves a remote, stark stretch of arid land as a U.S. wilderness area meant to remain largely undeveloped. The peak is the defining landmark of the area and gives the wilderness its name, reflecting the importance of both the landscape itself and its long-term protection.
