What a great cabin! The route that I took was NF-22 --> Champion Creek Rd. The vehicle that was driven was a FWD Mini Cooper. Before I left I called the Cottage Grove Ranger District to ask if a sedan could make the drive mentioned earlier and I was answered with a hesitant "yes". While this is correct I would not recommend this drive in a sedan unless you have experience muddin' or driving off road. Lots of opportunists were presented to high center and get your car stuck.
I would also recommend bringing a laminated sign that says the cabin is rented. It can be clipped to the welcome sign when you first enter the driveway to the cabin. If you don't you will get lots of visitors.
The cabin is two stories and can sleep a total of 10 people; eight on the 2nd floor and two on the 1st floor. No electricity or water is provided so don't forget your drinking water and lanterns. A proper wood burning cooking stove is provided in the main living room. The stove had two burners on the top and a oven big enough to cook a couple of pies. The dinning table can comfortable seat 8 people. The kitchen has a small table for preparing food and enough counter space to cook a meal big enough for 10 people. While the cabin does not have running water the sink does drain to the outside (some of the forest service cabins I have rented in the past have the sink drain into a bucket under the sink).
On the deck there is a firewood box with no wood in it. The outside area has a large picnicking table next to a fire ring and a 'mini" stove that you could cook food on with a pan.
Keep in mind that this cabin is located in a area where ATV's and dirt bikes are used and you will hear them. Other than that this is a great little cabin and I cant wait to come visit it again!
