Manhattan Beach is a hotspot for beach volleyball and surfing.
A majority of the land in Manhattan Beach was once exposed sand dunes which now lie beneath the city's buildings and streets. The underlying dunes afford residents ocean views throughout western portions of the city. The tallest hill is 244 feet high and located in the city's southwest region. The only remaining exposed sand dune is at Sand Dune Park, where sand resembling the original landscape can also be found. In the late 1920s, Manhattan Beach excess sand was purchased by Hawaiʻian developers, who negotiated a deal with the Kuhn Brothers Construction Company to ship the sand across the Pacific Ocean from Manhattan Beach via Los Angeles Harbor to Waikiki Beach over a 10 year period.
The beach is approximately 400 feet wide and 2.1 miles long. In the early part of the last century, the beach was narrow (approximately 150 feet) and sloping. From 1938 to 1989, it more than doubled in width when large quantities of sand were placed on beaches to the north during construction of the Hyperion Treatment Plant, Marina Del Rey, and Scattergood Power Plant. The sand was carried southward by the ocean's natural littoral flow and widened Manhattan Beach.
Every August, the city hosts the Manhattan Beach Open Volleyball Tournament and the International Surf Festival.
