Things To Do



Los Osos Oaks State Reserve, a 90-acre grove of dwarfed, 800-year-old coast live oaks, occupies an ancient dune habitat eight miles west of San Luis Obispo and five miles east of Morro Bay. This centuries-old oak woodland protects an unusual variety of plants, animals and biotic communities. Explore the cool, quiet surroundings of these moss-draped, fantastically gnarled trees, and let their enchantment surround you.
