This state recreation area has 3 spots for overnight parking (one night only, first come first served).  As this is a popular day use area for hikers and bikers,  you can't pull in until 3pm and you have to be out by 9am.  It's meant to be a quick overnight spot, not a camping destination.  Self contained vehicles only. No tents. $12 fee.

Even though you can't technically take the spot until the afternoon, you can hang out in the day use area until then. We didn't have to pay the $6 day use fee since we planned to stay the night, but that might have been at the ranger's discretion.

There are 3 spots available, but the middle spot has been closed temporarily due to covid.

There is a water faucet and some trash cans and plastic, glass, and aluminum recycling available, and there were porta potties when we were there but not sure if those are always there. There is a picnic table and grill at each spot. No fires.

Good cell service.  Near the freeway so there was road noise almost all night.

Great option for when you just need a cheap overnight.
