We stayed here in January. Cold, below freezing. However, the cabin was sealed well. Some broken windows were filled in with pillows. The cabin had water, a table, and some chairs. There were 3 inch mats for all the bunks. The outhouse has a fine view of the summit crater, but it's a little bit far from the cabin for night time visits. The 2 mile hike from the junction with observatory trail is relatively flat, but a surprisingly difficult hike due to the rough and rocky surface.
