Michigan's Upper Peninsula abounds with waterfalls! Many of those found within Pictured Rocks National Lakeshore are the result of water running over a shelf or cliff of hard limey sandstone called the Au Train Formation. This geologic formation resists erosion better than the softer sandstone layers just below it. Most of the park's main waterfalls can be accessed on foot. Please use caution while hiking to waterfalls. Stay on the trails and watch for uneven footing. Where permitted, pets must be on a 6-foot leash at all times. Pets are not permitted at all waterfalls.
