From tiny minnows to towering cattails, the ponds and streams on the North Shore offer our youngest guests a look at some of Mother Nature’s little things. We ventured to Hartley Nature Center in Duluth with glass jars, nets, magnifying glasses to get a closer look at some of the critters that call the beautiful 660-acre park home. Grab a kit from one of our resorts during your stay and help your kids build a life-long love of nature.
