No Reservations needed you just pay at the little pay station it's an awesome Park 50 inch maximum width on your machines
When you get there find your spot, you put your money in a envelope provided and tare off your receipt and drop it in the iron box there at the station
First come first serve.
I don't know for sure but I think it's 1st come 1st serve. It's not like there is a ton of camping spots and you will have to go without a shower. Only facility is a men and woman outhouse. Though as far as outhouses go they're very nice. There is phone number for Houston Valley but you will have to Google the number.
