A good spot to park the bike and go for a short hike: Adjacent to the Morro Bay estuary, the El Moro Elfin Forest in Los Osos is a 90-acre natural area belonging to San Luis Obispo County Parks and California State Parks. Its plant communities include coastal brackish marsh, riparian woodland fringe, pygmy oak woodland, maritime chaparral, and coastal dune scrub. The Elfin Forest supports more than 200 species of plants, as well as 110 kinds of birds, 22 species of mammals, and 13 species of reptiles and amphibians. It is home to rare plants, butterflies, snails, and birds. Chumash middens occur throughout the Elfin Forest. A four-fifths of a mile boardwalk loop constructed in 1999 provides wheelchair access and protects the Forest's sensitive habitat. The Los Osos/Morro Bay Chapter of Small Wilderness Area Preservation (SWAP), after being the prime mover in securing the lands, "adopted" the Forest in 1994. https://www.elfin-forest.org

Hazard Peak stands at 1,076 feet, making it one of the highest peaks in the area. Don't be misled by the name; it was named after Alexander Hazard, the previous landowner, and not because of any hazardous conditions. The views of the ocean and dunes from here are truly spectacular.
