The entire Gooseberry Falls State Park and campground were built in the 1930’s by the Civilian Conservation Corps. The stone work is amazing! There are great hiking trails along the waterfalls as well as away from the water along the Superior Trail (which was developed long after the CCC work ended). The campground has nice sized private campsites, newer and clean modern showers and bathrooms. The campground is very popular and fills up fast, so you might want to make reservations. Supposedly there are one or two kayak in sites at the mouth of the river, but I did not check it out. This park is VERY busy with visitors who want to see and play in the falls. But it is easy to escape the crowds- just head out on one of the hiking trails away from the falls and you will have the place to yourself.
