One of our most charming natural attractions can be found right at the center of the metropolitan sprawl. Just over the hill from noisy I-394, nestled in Wirth Park at the bottom of a hill, you'll find a sign for the Quaking Bog. Tucked away from the road, a short walk by trail, the bog is a true wilderness phenomenon—a thick layer of sphagnum moss suspended atop a five-acre acid bog. Visitors can access it via a floating walkway, so you can observe without disturbing. Look more closely and you'll notice a coat of Lilliputian undergrowth, saplings taking root, and plentiful wildflowers and ferns. The occasional Golden Valley home peeks through the thick Tamarack trees, which is about as much of the city as you'll see amid this still, lush park that's bursting with local wildlife. Dragonflies and frogs favor the bog, and the occasional duck finds its way from the chain of lakes. The Quaking Bog is the out-of-doors at its most accessible, a must-see for any day-tripper.
