Located adjacent to the city of Los Angeles, the second largest urban area in the United States, Santa Monica Mountains National Recreation Area protects one of the largest and most significant examples of Mediterranean-type ecosystems in the world. The climate of the Mediterranean ecosystem, characterized by wet winters and warm, dry summers, along with the diverse topography in the Santa Monica Mountains has created a landscape filled with unique natural resources.
The Santa Monica Mountains are part of the east-west trending Transverse Ranges of Southern California. The range is geologically complex and characterized by steep, rugged mountain slopes and canyons. Elevations range from sea level to more than 3,000 feet. The Santa Monica Mountains are adjacent to 46 miles of scenic California coastline with sandy beaches and rocky tide pools and lagoons.
