Torrey Pines State Natural Reserve is 2,000 acres of coastal state park located in the community of La Jolla, in San Diego, California, off North Torrey Pines Road. Although it is located within San Diego city limits, it remains one of the wildest stretches of land (8 km²) on the Southern California coast. It is bordered immediately on the south by Torrey Pines Municipal Golf Course and on the north by the city of Del Mar. The reserve was designated a National Natural Landmark in 1977.
The reserve consists of a plateau with cliffs that overlook Torrey Pines State Beach, and a lagoon that is vital to migrating seabirds. Many different kinds of wildlife and flora are found within the reserve, including bobcat, fox, skunk, raccoon, coyote, rabbit, cacti, coastal chaparral, and the rare Torrey pine. During their migration, it is sometimes possible to see several species of whale from the cliffs, including humpback whale and gray whale. The eight miles of trails within the park offer an attraction for hikers and beach-goers and a small museum sits at the top of the hill. From the cliffs or many places along the beach, it is possible to see La Jolla to the south and Del Mar to the north. At the southern end of the beach is a large rock that projects into the ocean, called Flat Rock. South of the rock is San Diego's unofficial nude beach, Black's Beach.
