Welcome to Sweet Springs Preserve in Los Osos, CA! The Morro Coast Audubon Society (MCAS) owns and manages this beautiful 32+ acres preserve since 1989. Sweet Springs offers short hiking trails, beautiful views of Morro Bay and Morro Rock, and excellent birding opportunities. The preserve is strictly dog-free to protect our many ground-nesting birds and other wildlife. On this page you will find highlights from our wildlife cameras that we have installed throughout Sweet Springs Preserve. This project was made possible through the generous support from our members!
