Came in early on a Friday afternoon to find the parking area vacant. Signage is clear: camping is only allowed in the designated area. No amenities, not even a dumpster or a pit toilet. Towards dusk a van pulled in. They were very quiet. But the parking lot is right on a paved 55 Mph Highway with quite a bit of traffic into the night, no trains or planes. Big rigs could easily get in and out of here but after three or four RVs it would be too crowded. No migrating waterfall here at the end of March, just a lot of mourning doves, ravens, and a couple of cows. Not bad for free. This is a state wildlife viewing area but no mention of any required permits
