We stayed two nights. I highly recommend making reservations online prior, but due to other issues, we had to take a chance with First Come First Serve. The loop road is about 3/4 of a mile. The sites are well spaced out and all are very spacious. Although the driveway begins at Marble Creek, there’s no access to the creek from the campground. There is, however, access to the Cascade River! No running water, so bring your own. We totally enjoyed our stay and would absolutely stay again.
