We stopped here on our way to north Minnesota. Originally we planned 2 days but really needed to rest so extended it to 4 days. It was a little hairy getting to, the 2 lane winding road with the raging river on one side did slow us down a bit.  The Rangers were friendly and accommodating. The park had taken quite a beating with the winter storm that had been there the previous week, a lot of sites were closed due to trees down and snow.  While we were there they were actively cleaning up, but left in the afternoon so we had no disturbances from saws or equipment noise. The water was not turned on yet for the season, so the bathroom/showers and dump station were not available.  There was a potable water source at the front of our loop to fill our fresh tank and our water storage cubes.  The sites were shaded well, and easy to back into.  We had to work a bit to get our camper level but that may have been due to the snow and water that was on the site so we figured it was par for the course.  We walked to the Welcome Center and the swinging bridge, there were multiple hiking trails accessible by the camping area.  It was relatively busy on the weekend but cleared out during the week.  We had lots of wildlife visitors.  The park is pet friendly.  We found affordable propane and a dump site closer to Duluth.
