The turquoise, Lake Superior water may appear to be soothing, but it is usually not warm enough for a swim. This probably explains the abundance of attractions dedicated to the Lake. They permit visitors to experience the Lake without really dipping into it.

The Great Lakes Aquarium is a controlled ecosystem that is modeled after the Great Lakes underwater habitats. It is the only aquarium in the United States that consists completely of freshwater. It features aquamarine life such as soft shell turtles, otters, rainbow trout, and sting rays.

If watching all those animals couped up in tanks is frustrating, visit the Superior National Forest. Visitors may have a closer glance at freshwater wildlife. Surface water covers almost 700 square miles of the forest that begins in the United States and ends in Canada. Many of the top ten hiking trails as ranked by Backpacker magazine exist in this forest.

Alternatively, take a shore excursion with one of the local Lake Superior boat expeditions. Aside from passing other water vessels, the tours offer endless coastline views and opportunities to see lighthouses. A few different companies offer boat tours of Lake Superior. Pick up a brochure in the hotel lobby or Duluth visitor's center.

If you've come to Duluth with an interest in shipping, two museums you'll want to visit are the Lake Superior Maritime Museum and the William A. Irvin floating museum. The Maritime museum is a free museum located at the base of the Aerial Lift Bridge on Duluth's ship canal. Run by the Army Corps of Engineers, it features exhibits detailing the history of shipping on the Great Lakes. Admission is free, and the television monitors inside the museum offer the latest news on ship arrivals and departures. The William A. Irvin is the former flagship of the U.S. Steel Great Lakes Fleet, and the guided tours allow you to see what life on the lakes is like. The admission also allows you to take self-guided tours of the neighboring Coast Guard cutter and tugboat.
