At the corner of Sepulveda and Westchester, 10-15 minutes walk from the airport. Small grass area across the road from which all movements on the Northern runways can be seen. Limited photography as arrivals are almost directly overhead, and you are facing South. When a small aircraft (CRJ, ERJ, 737, A320) isn't blocked by the trees, a 55mm or smaller size lens can be used for a nice shot. However, walking to under the approach lights and jaywalking across Lincoln Blvd. can yield some very nice shots of inbound aircraft. Parking in this area is limited (for those driving to the spot) depending on the time of day if you park on the street, and can be sparse during lunch hours (11:00am - 2:30pm).
There is a multi-story car park with good views from the top floor. No photography signs are present, and you will likely be told to leave.
