Trona Pinnacles Area of Critical Environmental Concern (ACEC) Adventures

Located in the California desert, the Trona Pinnacles Area of Critical Environmental Concern (ACEC) is managed by the Bureau of Land Management and spans nearly 4,200 acres. The area is famed for its dramatic and otherworldly landscape formed by more than 500 tufa spires—limestone formations created underwater during the Pleistocene epoch when the region was covered by Lake Searles. Pinnacles tower up to 140 feet above the dry lake bed, arranged on three prominent groups, creating a stark and captivating desert scene. The unique geology draws geologists, filmmakers, photographers, and outdoor enthusiasts alike. The site also provides critical habitat for desert wildlife, including species adapted to the arid environment such as desert kit foxes, coyotes, and various reptiles and birds. Visitors can explore the area through a network of unmarked paths and roads, ideal for hiking, off-road driving, mountain biking, and horseback riding. Camping is allowed but primitive, with no developed facilities nearby, enhancing the remote desert experience. The absence of paved trails invites visitors to explore freely while practicing Leave No Trace principles. Its remote location and rugged landscape make it a prized destination for those seeking solitude and photographic opportunities, especially during sunrise and sunset when pinnacles cast long, dramatic shadows. The area has also served as a popular filming location for science fiction and western movies due to its alien-like appearance and expansive views. While there are no visitor centers on-site, information is typically available at nearby BLM offices. The Trona Pinnacles ACEC stands out as a striking natural formation and an important protected desert environment with challenging access that rewards adventurers with rare beauty and peace.
