We stayed here for 2 nights in one of the Cabins in December. There is no electricity, bedding, or running water, but there is a propane heater that looks like a wood burning stove that casts a great ambiance. Our cabin also had plenty of coat racks, a snow shovel, and a table. We stayed in Cabin 6, and walked though 2 feet of snow 300 ft down a hill (larger hill than expected) with all our stuff to get settled in. As we approached, the propane stove was already going and the cabin was warm and inviting. We used string lights (solar powered) to provide light (there is a dim solar powered light in the cabin as well). We brought 0 degree sleeping bags in case the heater was not enough, but it was toasty warm inside and we ended up hot. The cabins are right on the edge of the reservoir (which is drained as of Dec 2021 but still beautiful in the snow). Cabins 1-3 (cabins 1&2 hold 15ish ppl for large groups, cabin 3 is ADA) are closer to the road and look like they would not have such a long walk in the snow. During my search, it looks like they also allow primitive camping in the winter for $18, but I didn't see which area this would be in, the cabins are on the north side of the lake. Daily vehicle fee of $9. The experience was incredible, we were completely alone and enjoyed great stars and beautiful sunrises. Highly recommend for a unique winter camping experience (sure it would be great in the summer as well but likely way more crowded). Be sure to be prepared for cold temps!
