Channel Island Harbor is located 5.8 miles southeast of Ventura Harbor and 1 mile northwest of Port Hueneme. There is a privately maintained lighted buoy about 1.1 nm west of the striped 209 foot stack that is .6 nm north of Mandalay Beach with a flashing red light atop the stack.  About .3 nm east of the the lighted buoy are 3 or 4 mooring buoys for the submarine pipeline running from shore.
There may be shoaling to the southeast of the south jetty at any time. The entrance between two jetties, both lighted, turns to the north and continues to a "Y" with both resulting channels ending at bridges that separate the main harbor from the "resident" docks.
There is a fog horn on the end of the south jetty.
