Rouky:I've never been there... so you better tell me what to look for unless you want my own maker to show it to me.
They usually only go to the Key-Hole on really calm days.
http://www.divebums.com/main.html look under dive sites, Los Coronados - Keyhole.
The Keyhole sits near the southern end of North Island, where several small openings exist in an archway connecting the main body of North Island to a smaller peak just south. Even on calm days the ocean swell, unobstructed for many hundreds of miles, pumps through these passthroughs. This is not a site for the inexperienced and not a site for anything but calm days. We had our compass reading wrong on the return, and got washed up against the walls.......hmmmm.
