You will be making this drive regularly, so it is worth learning the shortest version of it now. The school sits at 7900 Balboa Blvd on the west boundary of Van Nuys Airport, a block south of Roscoe Blvd. Almost everyone arrives on Balboa itself: north from the 101 through Encino and Lake Balboa, or south from the 118 above Granada Hills. Both approaches take you past the Sepulveda Basin or the golf courses respectively.
If you are coming from the far side of the Valley, Sherman Way, Victory Blvd and Roscoe Blvd all cut straight across and meet Balboa within a mile of the door, which usually beats a freeway detour. From Santa Clarita, the 405 south to the Roscoe exit is the standard run. From Pasadena and Glendale, the 134 west to the 101 north is reliable outside the evening peak on the Ventura Freeway.
Book your lessons for the early morning if you can. The air over the Valley is smoothest before the sea breeze builds, traffic on Balboa is light before eight, and you will be away before the day heats up. Whichever gate you use, put the street address rather than the airport name into a navigation app, because Balboa Blvd serves several separate airport entrances along its length, and only one of them is ours.
Parking is free and there is no barrier. Coming in from Balboa Blvd, turn right immediately and follow the road down to the visitor spaces; Suite 108A is on the hangar side, marked with the suite number.
