You are lucky if you find this park on the first approach. There are no signs. You will see a blue camping arrow on the 437 exit stop sign. Nothing after that until you realize you better call the park. The park will tell you, you are going to Billings. It turns out the park is at the Sinclair gas station by the stop sign. You will pull into a tiny, weary, old park made for 26' trailers. The sites are gravel and level. The electric is good for 30 amps. We are fortunate enough to have a 34', three slide motor home. We had a snug fit. We unhooked our tow and parked it in front as not to impede traffic. There are permanent people living in 26' trailers. It is a comfortable park. Grass but no shade. We camped here in a Motorhome.
Small park good for overnights. Some seasonal workers living in the park. Park is connected to a truck stop that has a good restaurant. The park is close to Billings Mt. Some smell from the refinery in the evening lasts about ten to twenty minutes. They have weekly and monthly rates. We camped here in a Motorhome.
