Stillwater and the St. Croix River Valley
A St. Croix River day from the Twin Cities: a riverside walk in William O'Brien State Park, a deli lunch and a sawmill-ruin stroll in tiny Marine on St. Croix, then Stillwater's Main Street, a walk across the 1931 Lift Bridge to Wisconsin and the view from Pioneer Park, with the permits, parking and 2026–27 bridge work to plan around.
