"User reviews present Manker Flats as a scenic, secluded campground that is well-suited for hiking and other nature-based activities. However, common complaints include noise from inconsiderate campers, maintenance issues with trash and vault toilets, and the presence of bears. The campground's rocky terrain and lack of flat sites have also been noted. While some visitors praise its affordability and proximity to trails, others cite frustrations with the first-come, first-served system and lack of peace during peak seasons."

Summer days bring warm sunshine filtering through pine boughs, while early fall paints the forest in golden light—both seasons ideal for camping adventures.

About Manker Flat Campground
Nestled high in the Angeles National Forest at 6,000 feet, Manker Flat Campground beckons adventurers seeking an authentic mountain escape. This rustic, first-come, first-served haven features 21 intimate campsites carved into the wilderness, each equipped with its own picnic table and fire ring where stories are shared under starlit skies. While RVs up to 16 feet can navigate these mountain roads, the campground's true charm lies in its simplicity—no hookups, just pure connection with nature. Vault toilets and the essentials are all you'll find here, leaving more room for what matters: direct access to legendary trails that wind toward the mighty Mt. Baldy summit and the cascading San Antonio Falls.
Manker Flats provides a traditional camping experience with 21 sites catering primarily to tent campers and smaller RVs. Sites operate on a first-come, first-served basis and are open year-round, though winter access may be restricted due to snow.
Historical SignificanceThe land around Manker Flat whispers stories of those who came before. Long cherished by Native American peoples who first traversed these mountain paths, the area now cradles pieces of more recent history. Just down the mountain in Mt. Baldy Village, the historic Mt. Baldy Schoolhouse stands as a testament to the hardy souls who made these heights their home. Today's Visitor Center, housed in these historic walls, bridges past and present, offering modern explorers a glimpse into the rich tapestry of human connection to these sacred peaks.
Weather and SeasonsThe mountain's moods shift dramatically with the seasons at Manker Flat. Summer days bring warm sunshine filtering through pine boughs, while early fall paints the forest in golden light—both seasons ideal for camping adventures. When winter arrives, the campground transforms into a frozen wonderland where snow and ice often limit access, creating an exclusive retreat for the most determined cold-weather campers. Spring awakens the forest with cool, crisp air and gentle breezes that carry the scent of new growth, making it a perfect time for those seeking solitude before summer crowds arrive.
ElevationPerched at 6,000 feet where the air grows thin and crisp, Manker Flat offers a true mountain refuge far above the valley floor. Here, your lungs work a little harder, but the reward is air so pure it seems to cleanse your soul. The elevation brings a natural air conditioning that provides blessed relief from summer heat below, while creating a landscape where alpine and foothill ecosystems merge in fascinating ways. First-time mountain visitors should pace themselves as they adjust to the altitude, but the slight breathlessness is a small price for the dramatic vistas and cooler temperatures.
Natural Features and SceneryA living cathedral of towering Incense cedars, stately Ponderosa and Jeffrey pines creates a aromatic canopy above Manker Flat, while sturdy oaks add their ancient wisdom to the forest tapestry. The campground's relatively flat terrain, scattered with weathered granite boulders, tells the geological story of eons past. Big Butch Wash meanders nearby, its seasonal waters providing a soundtrack of mountain music when flowing. Every direction offers a postcard view—whether gazing up at craggy peaks or down into verdant canyons where morning mist dances among the trees.
Geological RegionManker Flat claims its place within the dramatic San Gabriel Mountains, a young and dynamic range that forms the stunning backdrop of the Angeles National Forest. At 6,000 feet, the campground occupies a unique ecological niche where mountain geology meets forest biology. The rocky substrate speaks of ancient tectonic forces that thrust these peaks skyward, while the magnificent stands of Incense cedar, Ponderosa and Jeffrey pines, along with resilient oaks, demonstrate nature's ability to flourish in this elevated realm. This is where the raw power of geological time meets the patient persistence of forest succession, creating a landscape both rugged and remarkably alive.
