This is my first wildcamping/boondocking location, but I loved it. It feels like you're right in the middle of the forest! It's a wide dirt pullout with room for 7-10 cars. And although it's right alongside the road, it's not a super busy road like some highway spots, so it felt pretty secluded and quiet. Very few cars at night.
No signs of any kind indicating "no parking." 1 bar of Verizon LTE.
The dirt was solid -- I wasn't worried at all about getting stuck in the mud (and I'm here in the middle of winter with tons of recent rain). Plenty of room to turn around with ease.
And you're right at a hiking trail that takes you to beautiful falls!! What more could you ask for? -- Don't make the mistake I did. The trail all the way on the left side of the parking lot takes you to the falls. The trails in the middle of the lot are super steep and muddy and don't lead to the falls.
Only downside is it's not perfectly flat. It wasn't too bad though. I just parked with my head pointing uphill when I go to bed, of course.
There is also another option down the road to the east about 500 feet. It's a paved pullout, but it is smaller so it doesn't have as much space to turnaround.
