William O'Brien State Park Professional Review and Guide

"William O’Brien State Park is a popular—and easily accessible—recreation area conveniently located just one hour east of the Twin Cities. Here, the St. Croix River, designated a wild and scenic river, stretches for miles until it joins the Mississippi downstream.

The featured hiking trail encompasses much of the park, skirting ponds and marshes and traveling through a landscape of rolling meadows, restored prairies and oak savannas, and stands of white and red pines. A trail leading off the main trail crosses Highway 95 to take you to the river and additional recreational options. This park is a favorite among canoeing and boating enthusiasts because of its access to the St. Croix."
