There's a pay lot, but parking isn't enforced until 9:30 am.
I am pretty for a fact you can just drive up there and park wherever. I never drove up but walked 100 times and an a weekday its not uncommon to be the only person there watching sun rise. Last time a couple weeks ago there was just me foe like half hour then 1 more guy showed up. I doubt there can be any parking enforcement at sun rise time especially.
