Incredible views and a great place to stay!
We stayed two nights, and, though we didn't find any extra mantles for the gas-powered lights, the cabin was clean and the toilet, honestly, smelled fabulous!
The individual (Sarah?) staffing the lookout tower was very nice, too. As everyone says, the last mile to the cabin is somewhat steep and rocky, so make sure you have a vehicle with decent clearance and tires. My partner and I borrowed a Jeep Compass and didn't have any issues, and the lookout drove a Ford Ranger.
We definitely hope to visit again. :)
