Sunset Marina Park first opened its facilities in 1969. Prior to that, the area was an undeveloped natural waterway adjacent to the huge wildlife area that is still untouched. The park itself includes a 276 slip marina, a public boat launch ramp with multiple lanes, boat and trailer parking, car parking areas, a boat repair yard and public picnic areas.
The Orange County Sheriff's Department Harbor Patrol office is located within the confines of the Sunset Marina Park at the West end of Orange County. This area was originally known as Sunset Aquatic park. The Harbor Patrol is staffed 24 hours a day and is located in a temporary facility near the public boat launch ramp.
