The Wave Organ is a "wave-activated acoustic sculpture" built in 1986 by Peter Richards and George Gonzales in collaboration with the San Francisco Exploratorium.

The Wave Organ is located at the end of a jetty in the Golden Gate Yacht Club and gives a near perfect view of the Golden Gate Bridge and Alcatraz. The jetty itself was constructed with debris from the demolished Laurel Hill Cemetery and these marble fragments were worked into the Wave Organ's construction. The sound activated component of the installation is comprised of twenty five PVC and concrete "organ pipes" of various lengths and elevations within the greater site. Each pipe, due to it's unique length and elevation, makes a unique rumble, gurgle, slosh, hiss, or splash as water moves in and out of the pipe.

The Wave Organ is best visited at high tide.

To get there, head west on Marina Blvd and make a right on Lyon. Continue down Yacht Road to the very end of the jetty.
