When is the park most crowded: days, times? Is there a place to have a picnic lunch? Are the bathrooms open?

I was there two weeks ago on a Saturday. I got there at noon and it was fairly busy at the mail visitor area. $10 day parking fee. The bathrooms are open and relatively clean. There are 4 picnic areas and 4 parking lots that you can use. We left around 5pm. Seem like there were more cars/people at that time. Hope this helps.

There are four bathrooms there, plenty of space, low crowds, and spectacular settings. Just bring a mask for etiquette. Enjoy 😉
