c2j, you are correct. I think you must have inspired the song "I've been everywhere."
I've just been on a day-trip to Corregidor, and so it was an obvious choice.
The long ridge in the distance is the largest part of island, where all the coastal batteries and barracks are. The slightly closer, darker and smaller ridge is the hill which contains the famous Malinta Tunnel.
Here is what looks like a posed photo of Ki-21 Sally bombers over Corregidor. Kindley Field is at the bottom left.
Over to you.
