Govt Wash is my favorite place to stay in the wintertime. Temperature is manageable without auxiliary heat in my van.. 70s in the day, not below 40 at night through January. Love the views of the lake. Feels so far out but only 30 mins to Vegas. Henderson for groceries and gas is very close. Lots of coyotes, even during the day. Be mindful of that if you have a dog along with you. Free dispersed camping here (with NPs Pass) with bathrooms and dumpsters at entrance. Washboard road isn’t too bad, and you get get pretty close to the lake even without 4x4. I loveeee being here. Sunsets and sunrises are awesome.
