Not sure what happened to my response. I had mentioned that there was once a great parking lot for watching the aircraft taking off on Runways 11 but that has been closed to make way for police station.
The Bayfront Park, as mentioned above, is a good place also.
North Access Road: I haven’t been on this road for a while. It should still be opened because it leads to the Coast Guard Station and cargo areas. Not too much to see.
If you go to the East Bay, the San Leandro Marina is great for spotting aircraft landing at OAK. If you are photographing, the morning is the best time because the sun is behind the aircraft in the afternoon. Check flightaware.com/live/airport/KOAK for aircraft you’re likely to see at OAK.
The Oakland Western Aerospace Museum is a must-see if you make to OAK.
