Great Marsh Trail

The featured hike starts from the south parking lot trailhead. Follow the trail generally north until the T-junction. Turn right and complete the lollipop shaped trail. Return to the T-junction and head straight this time to the Great Marsh observation desk. Lastly, hike back to the T-junction and turn right, which will take you back to the south parking lot. The Great Marsh is the largest interdunal wetland in the Lake Michigan watershed. It serves as a critical habitat for breeding and migratory birds. This popular trail features an overlook of the marsh where you can spot a wide variety of birds ranging from Great Blue Herons to Sandhill Cranes. While much of the marsh was drained in the early 1900s for residential and agricultural use, the National Park Service began restoration of this portion in 1998. Flocks of coots, mallards, and wood ducks now glide over the wetland's surface. Kingfishers, tree swallows, and rusty blackbirds rest during migration. Green herons stalk the shoreline while beaver play in the channels. The Great Marsh abounds in the diverse animal activity of a healthy wetland ecosystem. During the migration periods, the wetland will be frequented by flocks of ducks and geese. The wading birds like herons and egrets, and the songbirds such as warblers and red-winged black birds are abundant. - Open daily from 6:00 am to 11:00 pm. - Free (no entrance or parking fees). - Bicycles and motorized vehicles are not allowed. - Respect closed area signs. - Information board at the trailhead. - Trail surface is grass with some sections of packed dirt. - No restrooms or potable water. - Main trailhead is at the south gravel parking lot. - This trail features a short, paved wheelchair-accessible trail to an overlook of the marsh from the north parking lot. - Pets are permitted on a leash (6’ or shorter). - Wear adequate footwear as the trail can be muddy and slippery in sections. - Stay on the trail to protect the wildlife and yourself. - Prevent tick bites and related diseases by using insect repellent.
