Park outside gate ,it only adds a short additional walk so you can't get locked in.But note the rules say you can't stay after the designated time
I just asked a City of Phoenix park ranger. You can remain in the park until 11pm.
Agreed no ticket... Will get locked in after 11 if not careful. Remember you are a blinding Beacon of light with your headlamps after Sunset so they will find you if you're there after 11
There is a gate that closes automatically at closing time
We stayed well past sunset with no problems.
You won't get a ticket.
We go to watch the sunset all the time. They lock the entrance gate and have spikes to prevent people coming after. We have never had a problem.
I've never been there that late, but I do remember seeing a gate. So probably they close it at night
