I would agree with the previous poster, as a campsite this is no great shake. We we where there during the mudweek in July there was only one orher person there so it was quiet, but there was evidence of weekend campers who didn’t practice “Leave no Trace” camping. We bisited this park for historic reasons, due to the important regional treaty signed here and as it was a crossing point on the historic trade route to old Fort Pembina. There is a nice memorial to the treaty event, and it is a nice stopping point if you are following the route of the Pembina Trail. I wouldnt suggest it as a camping destination it snd of itself, but it is ok for camping as as stopover, or it would be good if you planned a couple day trips paddling on the river. It wiuld also be good as a spot for a group canping event, like a family reunion of scouting event, however I dont think you can reserve ahead of time and summertime likely has a lot of day use picnicers on weekends.
Camping is free, no reservations required. The unfortunate side effect, sometimes, is camping around irresponsible campers. Avoid major holidays. Besides that one issue the campsite allows tents and RV's, has latrines, and a boat/canoe launch on the Red Lake River. Each site has a picnic table, fire pit and trash barrel nearby. There are some sites with trees for hammockers.
