Red Rock Canyon SP was a nice stopover on a Monday night heading towards DVNP. Only a handful of campers, quiet. Downside is that the Hwy. is in view about 3.5 miles out. No road noise really, just the lights can be seen where you are camped up against the rock bluffs. Nice hike in the morning back out at the Hwy. The rock is increasingly red with a nice loop trail & some good strata & formations. We continued past the loop down the wash a bit for a little more scenery.
