We hiked there sunday afternoon. Beautiful day. The park had a troop of boyscouts there, but we only saw them near the parking area. No camping was available, they were full, but we travelled there on our hogs to hike it anyway.
If it has been raining, you may be unable to cross into the area of the trails, or more importantly, cross back out to your car.
Look forward to going back, Next time we'll reserve a campsite.
