We had a reservation for the night at Mazama, which NPS cancelled <24 hours prior to our arrival so we were left scrambling for another place to stay. This campground was on the list of outside-of-the-park alternatives, and we were able to grab a site (one of several that were available) when we arrived around 6pm. The campsite was nice and right along the creek, the water tasted great, and it's relatively close to Crater Lake.
