Located on the edge of one of the largest and busiest ports in the world, the Cabrillo Beach Coastal Park is comprised of several seashore habitats found in Southern California. All are within easy walking distance of each other near the main channel of the Port of Los Angeles. They include a windswept beach and a protected harbor beach separated by one of the largest breakwaters in the world, as well as tide pools, a fishing pier, a man-made mudflat, and coastal cliffs that provide living spaces for coastal marine organisms. The combination of natural and man-made habitats here bordering the San Pedro neighborhood of the huge metropolis of Los Angeles makes this an unusual environment, representative of an urban ocean.
