First off, I think people are afraid to leave honest reviews. Probably due to this Park's location. I will be as objective as possible.

We found this on Dyrt, thankfully, as we were driving 1300 miles home from Glacier. This had openings, and was on Flathead Lake. Huge win there.

We pull up, and the girl working there gave us both a brief look that we both thought was a bit strange. We didnt think much of it. There were several cameras at the entrance. We paid $35 and went to our lake front campsite. We set up quick, and went to use the bathroom. My girlfriend said there was blood all over the floor in hers. The men's had 3 adolescents hanging out in there. They weren't particularly friendly, but not rude either. They were charging their phones. There were bugs everywhere, including the showers. I wouldnt use the shower here. I was about to leave the bathroom, and a crying child came in. I asked what happened and he wouldn't tell me.

We got back to our site, and my girlfriend started crying. This was a unique experience, as we do a fair bit of camping, and haven't experienced anything like this. As this is happening, a 30-something man comes around the corner flipping some sort of ninja stick around. He wasnt threatening, but that added to the already somewhat bizarre experience. He ended making 4 or 5 laps around, but was ultimately minding his own business.

If you are not Native American, you will most likely be a minority here. This might bother some people. I personally dont care, and even enjoy being exposed to other cultures.

TL;DR: This has the feel of a public park, on a reservation, with campsites. Affordable and available lakefront camping. I'd camp here again, but I may not count on super restful sleep. It wouldn't be my first option, and I'd feel better having something to protect myself.
