Drove there today and found the gate locked with no attendant. Appears to be closed. A call to the number listed on the url produced a recording from September 2020 stating the park was open, but the number of sites was limited.

Very good view of (but not access to) the Mississippi River here. Nice grounds, lookout tower, playground, and they have a bath house available but we did not go in it. Several people camping around, including some tents but not full. Paid $25 for one night. Did not have sewer. Water from hose was tinted brown so we were afraid to drink it. Some sites have 50 amp and some have 30.
