All the pads were concrete and very level requiring very little leveling. The views were excellent as we were on the point near the Mississippi. Would like to have water nearer the coach but we came prepared with our own holding tank of water. Facilities were excellent for showering and bathrooms.

This is a really nice spot. It's close to the Mississippi River - you can walk right up to the water's edge. The sites were level and spacious. The park was clean and well kept. Most of the campers were families and everyone seemed well behaved. There was a vault toilet right in the camp area, with the more modern facility with showers up the hill away from the water, presumably to protect from flooding.

Thompson is a well cared for Park, the sites are wide and long many have concrete and level pads. Buy all means if you have a choice between a state park and one run be the Army Core take the Army Core.
