No reservation...Don't bother going here.
I read up on this park and planned it into my route based on everything I read. It looked like a nice place. Nothing I read indicated a reservation was required. It did look a little pricey for a campground but still cheaper than a hotel. I arrived early enough to set camp before dark. Got to the gate and was told if I did not have a reservation, I could not enter. I was on a motorcycle/trike. They claimed they were absolutely booked and had no room for a tent. Yet there was a lot of vehicles in line behind me. I watched and those vehicles were all allowed in. I feel this park is not motorcycle friendly. Not very welcoming to travelers. I then drove into Lubbock and got a hotel for twice the price of camping. Not happy. Very disappointed in this place. Not hospitable to long-distance travelers. I do not recommend this place. I will never bother to visit this park again.
