Sunset Cliffs is a neighborhood on the western edge of Point Loma bordering the Pacific Ocean about 7.5 miles (12 km) south of La Jolla and 5 miles (8 km) west of downtown San Diego, California. The area takes its name from the sheer cliffs that line the coast, long a spot for watching the sunset. Sunset Cliffs Natural Park, dedicated in 1983, is a 68-acre (28 ha) coastal strip between the ocean and Sunset Cliffs Boulevard, connected to the 640-acre (260 ha) Point Loma Reserve. The park includes carved coastal bluffs, arches, and sea caves.

American Kumeyaay Indians traveled along Sunset Cliffs to gather seafood from the intertidal beaches below and collected various terrestrial plants in the area. During the 1915 Panama–California Exposition, sporting-goods magnate Albert Spalding developed a section of the cliffs, building bridges, trails, benches, and a stairway to the ocean; he called his estate Sunset Cliffs Park, a name later given to the neighborhood. In 1925 John P. Mills bought the property and surrounding land and developed it into a residential neighborhood; the City of San Diego subsequently acquired the former Spalding property from Mills and turned the coastal strip into a city park.

The Sunset Cliffs area is pocked with a dense network of caves. Above the cliffs is a strikingly circular hole, or littoral sink (also called a punchbowl), formed by a collapsed sea cave. About 40 feet (12 m) deep, it leads to a short sea cave with a single seaward entrance, cut into the thin-bedded marine siltstone and sandstone of the Point Loma Formation. Farther north, a larger littoral sink known as the Devil’s Pot was a popular tourist attraction for decades and appears on a 1910 hand-colored postcard, though it has since eroded away.  Read more here and here.
