Rush Lake State Natural Area

Rush Lake State Natural Area is a hidden gem for nature lovers craving solitude and serious birdwatching. This shallow, 3,000-acre marsh in Winnebago County is one of Wisconsin’s largest wetlands, home to cranes, herons, terns, and more. With wildflowers, cattails, and open skies, it’s perfect for peaceful paddling, birding, or just zoning out with nature. Access is limited—no trails or facilities—so bring your own gear and plan ahead. Best visited during migration seasons, this spot offers a raw, unfiltered slice of wetland magic that’s worth the detour.
