If you take the 105 West until the road ends at the beach, you will end up exactly in the parking lot. This is a great beach to go hang out at night and have a bonfire or a bbq in the firepits (they're all up and down the beach right off of the parking lot and RV park). It gets pretty chilly at night so bring something warm and it's noisy b/c of the airplanes taking off from LAX, but it's definitely a lot of fun anyways. The beach is kept clean for the most part. Parking in the lot is relatively cheap from what I recall, but you can find free parking along the road if you don't mind walking a long way to get to the fire pits (and make sure you move your car by 10pm...they start ticketing AT 10).
