This is open year round and I would not say it's hugely populated. There is vault toilets but not much else. It's so wonderful just to drive up to a spot on the river and camp, what's better is it is free! The stars are wonderful here, as there isn't much light pollution. The canyons show an interesting history. In the spring the wildflowers are truly a site to see! Watch for snakes and cats! Make sure you bring everything you need, there isn't anything near by. Road in is gravel, take it slow.
