Black River was gorgeous and a great float. However, this review is for the campground, which is zero stars across the board.
Upon check in, the older lady with gray hair at the front desk was extremely rude. After attempting to clarify the price and charges multiple times (of which she herself couldn't calculate) she made rude comments about me, in front of me, directed towards my wife. She then threatened to cancel our reservation. She rudely then told us to wait for the cardholder to be present (we were the first to check in among our group).
The entire front desk seemed unorganized - everything is pen and paper and calculator. I never was complaining nor was I upset about the pricing- I was simply trying to clarify what rates were being charged and she took great offense to this.
One of our group is also military, and when more of the party showed up, she refused to honor military discount, because the cardholder specifically wasn't military. She wouldn't even give the one military member a discount on his solo camping rate!
The campground was also disappointing. Dirty, rocky, and small. The bathrooms were disgusting and not well kept. The women's bathroom was constantly out of soap and toilet paper.
Overall, a terrible experience. I would 100% float the Black River again, however I would 100% not stay here again.
