Arriving just before the long weekend, we found a large and open (with some tree coverage) site across the road from the river. There were a lot of people arriving over the weekend and while it was "celebratory" in nature with some large family gatherings (to be expected anywhere on a long weekend), overall it was quiet, well spaced, well equipped (porta potties nearby and very clean), and well kept up (mowed, etc.). The road was a bit rough and we didn't go as far as we would have liked due to that. The folks at the greeting station were friendly, although when we arrived it was a bit tough to figure out where we should be going.
As others have mentioned, the campground - being in its earlier stages - is a bit rough around the edges but we could clearly see the intent and potential. That said, for me personally, I respect and value that it is an Indigenous-owned campground on Nation land and was happy to contribute towards it's success.
