I would like to go around 6pm at night do u think i would have a problem going at that hour?

You Should Have No Worries, I Would Go, Just Less Day Light To See, & WorkOut With.

i would like to go around 7pm, would there bere parking lot to park my car?

There are always people there well after sunset.

I agree with the consensus! But since it will be a bit dim at that time I would advise using a headlight.

Should be closed Dusk till Dawn, it's pushing it this time of year but probably would be okay

6pm should be fine.
