State Natural Reserves have outstanding or unusual natural or scenic values. Torrey Pines State Natural Reserve is a wilderness island in an urban sea. This fragile environment is the home of our nation's rarest pine tree - Pinus torreyana. Once this tree covered a larger area. It now grows only here and on Santa Rosa Island off the coast near Santa Barbara. The park preserves not only the trees, but also one of the last salt marshes and waterfowl refuges in Southern California. The reserve features high broken cliffs and deep ravines on headlands overlooking the ocean. Hikers can follow trails through stands of wind-sculpted pines. A picturesque, pueblo-style structure that served as a restaurant when it was built in 1923 houses the visitor center, featuring interpretive displays. Picnicking and camping are prohibited in the reserve. The reserve's rich plant community features wildflowers in the spring and visitors can see the California quail gathered in coveys in the early mornings of fall and winter.
