Agua Tibia Wilderness

Located in Riverside County, California, the Agua Tibia Wilderness spans steep canyons, rocky ridges, and a variety of habitats ranging from coastal sage scrub to oak and pine woodlands. Established in 1975, this 17,961-acre wilderness area lies within the Cleveland National Forest and incorporates some of Southern California’s most challenging and remote terrain. The name 'Agua Tibia' translates to 'warm water' in Spanish, referencing the nearby warm springs historically valued by Native Americans and early settlers. The wilderness is known for its rugged topography, with elevations ranging from around 1,400 feet to over 4,000 feet atop Agua Tibia Mountain, the highest peak in the area. Diverse flora includes chamise, manzanita, and California black oak, supporting a variety of wildlife such as mule deer, bobcats, and several bird species including peregrine falcons and California gnatcatchers. Popular recreation activities focus on hiking, backpacking, wildlife viewing, and horseback riding. The wilderness features several challenging trail systems including the southern terminus of the Pacific Crest Trail and the popular Margarita Trail. With limited water sources and no developed campgrounds, visitors find a true backcountry experience. Areas like Coldwater and Deer Springs serve as access points to trailheads. Due to its rugged character and remoteness, Agua Tibia Wilderness attracts outdoor enthusiasts seeking solitude away from crowded urban areas, while offering breathtaking vistas and natural diversity representative of Southern California’s wild landscapes.
