Spirit Mountain, Duluth

Descend any of Spirit Mountain's slopes, and you may feel like you're in the middle of a postcard. That's because the inclines rise above Lake Superior and St. Louis Bay, granting guests full glimpses of the picturesque bodies of water. It's just one of the things that sets Spirit Mountain apart from other outdoor recreation parks. A few more of those things: a zip line that whips through the treetops, an alpine coaster called the Timber Twister, and a 9-hole mini-golf course.
