Two visits here... The first one was awesome. No issues. Second one, we were told to vacate by a ranger within 5 minutes of arriving. There is no signage, but to reach the campsites you have to drive around barriers on some well-worn tracks that we were verbally told are "illegal roads". For what it's worth, the ranger was very cool about it... At your own risk, but if you do I'd definitely suggest picking a spot that is not visible from the main road.
