We spent a full day exploring Crater Lake and needed a place to stay for the night.  Since the campgrounds within the national park were closed for the season, we searched The Dyrt for a nearby place to set up camp before dark, and found nearby Annie Creek Sno-Park. It's a big parking lot with a vault toilet, a warming station with indoor picnic benches and a few fire rings outside.  There are also a few spots down by the creek, which might be fine for tent camping, but not suitable for larger vehicles.  There were several other campers when we stayed in early October, and we enjoyed watching shooting stars and roasting marshmallows together around a campfire.  Convenient location and perfectly fine for a night.
