In September 2016 we stayed two nights in Big Bear, CA. We had rented a cabin from “Cabins 4 Less.” These cabins were clean and well stocked. Check out their website http://www.bigbearcabins4less.com. These cabins have basic items for you to use. In the bathroom and in the kitchen (pots,toilet paper,soap,mugs). They are heated and they have hot water!! You just need to bring your sheets and blankets. They are also pet friendly. Its only $9.00 for your pet to stay with you. If you leave the place clean there is no cleaning fee.
During the day, the air was brisk and in the evening it dipped down to less than 37 degrees. It was cold!!! Bring extra blankets and jackets you are going to use them.
