About
Nestled along the scenic St. Croix River, a federally protected Wild and Scenic River, William O'Brien State Park stands as a cherished natural haven just an hour's drive from the bustling Twin Cities metropolitan area. Established as Minnesota's first metro-area state park, it offers a refreshing retreat across diverse landscapes, from undulating prairies and dense forests to vital wetlands and tranquil bogs. This expansive park invites visitors to immerse themselves in a rich tapestry of natural beauty, providing a perfect backdrop for outdoor recreation and quiet contemplation alike.
The park boasts an impressive network of 12 miles of hiking trails, each winding through unique habitats. The 1.6-mile Riverside Trail is fully accessible and offers serene views of the St. Croix River, the charming Lake Alice, and towering 100-year-old eastern white pines. Keep an eye out for White-tailed Deer gracefully moving through the woods or the vibrant colors of an American Goldfinch flitting among the trees. The Prairie Overlook Trail, with its rolling oak savanna and prairie habitat, rewards hikers with panoramic vistas of the St. Croix Valley and a chance to spot wildflowers like black-eyed Susans and wild bergamot. In the spring, the forest floor comes alive with rue anemone, bloodroot, and Eastern Skunk Cabbage, while marsh marigolds add splashes of yellow to wetland areas.
William O'Brien State Park is a truly memorable destination, offering a serene escape that reconnects visitors with nature throughout the year. Whether you're paddling a canoe or kayak on the gentle currents of the St. Croix, fishing for walleye or trout, or simply strolling the trails, the park's vibrant ecosystem is a constant source of wonder. The opportunities for birdwatching are exceptional, with the St. Croix River serving as a significant migratory pathway, attracting species such as the Tree Swallow and Song Sparrow. From observing Northern Leopard Frogs near the water's edge to discovering an active American Beaver lodge in the early evening, the park's abundant wildlife makes every visit a unique and enriching experience.

The St. Croix River valley, home to what is now William O'Brien State Park, was historically inhabited by the Dakota and Ojibwe tribes, who utilized its rich resources for centuries. European fur traders arrived in the 17th century, followed by extensive logging operations in the mid-1800s that cleared vast stands of white pine. After the logging boom subsided, lumber baron William O'Brien acquired much of this land for his personal estate. The park's foundation was laid in 1945 when William O'Brien's daughter, Alice O'Brien, generously donated 180 acres of land along the riverfront to the state in memory of her father. This donation led to the park's official establishment in 1947, making it the first state park in the Minneapolis-St. Paul metropolitan area. Over the decades, the park expanded significantly through additional land acquisitions, including efforts championed by leaders like Samuel H. Morgan, growing to protect 1,520 acres of diverse natural landscapes. William O'Brien State Park has recently undergone major accessibility upgrades to its day-use areas, with improvements completed by mid-June 2025, ensuring a more inclusive experience for all visitors.
