Think there’s no wide-open countryside left in Los Angeles? Think again. The Santa Monica Mountains stretch for 80km across the northwestern boundary of the Los Angeles basin. Within the range lie more than 60,000 largely undeveloped hectares of grassy swales, rock-studded hillsides, tree-shaded glens, and windswept beaches. A mosaic of state, local, and federal preserves protects this land, all managed under the umbrella of Santa Monica Mountains National Recreation Area, the nation’s largest urban national park.
One of the few mountain ranges in the United States to run east to west rather than north to south, the Santa Monicas can claim big nature bragging rights. Considered to be a “botanical island” in L.A.’s urban corridor, the slopes that run straight down to the Pacific are covered in chaparral, coastal sage, springtime wildflowers, and oak and sycamore forests. More than 20 species of endangered plants and animals thrive here. This is a place where you might see a bobcat stalk its prey, a coyote lope across the grasslands, or a golden eagle fly overhead.
