Cabrillo Beach
 

Does anyone know if the Cabrillo Beach launch is open at night?

Found the answer to my question. Just for those that were also wondering.

Parking is available at Cabrillo Beach. The parking lot opens at 5 AM and closes at 10 PM. Parking is free for the first 20 minutes and then is $1.00/hr to a maximum of $9.00 per day. Payment is made in cash.
Cabrillo Beach has a paved boat launch ramp. The boat lauch ramp is best reached from Shoshonean Road off Via Cabrillo Marina. The boat launch ramp and parking lot open at 5 AM and closes at 10 PM. Parking is $2.00/hr for vehicle and boat trailer to a maximum of $15.00 per day. There is no extra charge for the boat launch ramp. Vehicles with a boat trailer attached may be left over night or for several days at $15.00 per day. Vehicles without a boat trailer attach cannot be left over night and may be towed if left past 10 PM. Payment is made in cash.

You can park outside for free but parking is pretty limited. The walk down to the beach isn't bad, its the uphill walk that will kick your ass.
