The St. Croix River from Stillwater south to the confluence with the Mississippi provides the best conditions and facilities for sailing enthusiasts. This stretch of the river is wide with very little current. During the summer, weekend boat traffic on the St. Croix becomes quite heavy, providing a challenge for sailors. Weekdays provide the best opportunity for a relaxed sailing experience. Small sailboats can venture a little further north on the river.

Several marinas along the lower St. Croix provide slip rentals and service. The National Park Service does not endorse one marina over another. A list may be found at Boating.
