Foster Falls trailhead gate?

I've only been twice, and during the day, so I didn't notice if there is a gate at the trailhead parking lot or not. I'm assuming so. I could only find info on the nearby campground hours--what time does the trailhead close? I'm planning a trip to arrive late (not too late) on a Friday night to hike into Father Adamz.

as i recall there is a gate and they do close it at "sunset" Its been a few years since ive been there. i'd call the campground.
