Located on the mighty Mississippi River north of Fountain City, Merrick State Park is an angler’s paradise and a haven for water lovers. Known for its intricate maze of backwaters, islands, and sloughs, the park offers a peaceful riverside experience where the boundary between land and water blurs. It’s the perfect spot to launch a boat, cast a line, or simply watch the great river roll by.

Mississippi Access

Direct access to the Upper Mississippi River National Wildlife and Fish Refuge for endless boating and exploration.

Island Camping

Experience unique island campsites that allow you to moor your boat right at your “front door.”

Prime Fishing

A hotspot for walleye, panfish, and northern pike, known locally for its productive backwater lagoons.


Life on the River

Merrick State Park is defined by the Mississippi. The park’s geography is low and lush, consisting of floodplain forests that teem with wildlife. Egrets, herons, and bald eagles are common sights, making it a fantastic destination for birdwatchers. The quiet backwaters are ideal for canoeing and kayaking, allowing paddlers to drift silently through nature’s wetland corridors.

Wildlife Watch

Keep your eyes peeled for river otters playing in the sloughs and muskrats building their lodges along the banks. The spring and fall migrations bring thousands of waterfowl to the area.

Camping and Family Fun

The park is family-friendly, offering two campgrounds with a mix of electric and non-electric sites. The Island Campground is particularly special, offering waterfront sites that are highly sought after. A nature center offers educational programs during the summer, and the park’s miles of hiking trails provide easy, level walks suitable for all ages.
