Marina Location

Sunnyside Marina is the premier marina on the St. Croix River, just south of the historic lift bridge in Stillwater, MN.

To the North:
Travel the St. Croix river past Stillwater and enjoy numerous islands, limestone bluffs, and incredible natural scenery.

To the South:
The St. Croix river runs through Bayport, Hudson, and Afton and joins with the Mississippi river in Prescott.

There are opportunities in either direction of the marina for recreational boating, fishing, cruising, anchoring, and beaching. The St. Croix River is a nationally protected river and has been designated by Congress as a Wild and Scenic River.

Highlights

Biking Trails:
Enjoy a six mile bike ride on the scenic Loop Trail. Head up the MN side of the river using the Brown Creek Trail, cross the pedestrian lift bridge in Stillwater, go down old WIS 64, and then back across on the new Highway 36 bridge. Feeling like a day trip? Take the Gateway Trail 18 miles to St. Paul.

Stillwater:
Take a leisurely one mile stroll along the river on a paved trail to historic Stillwater. Go aboard a paddle wheel riverboat, meander through the many antique and boutique shops, choose from a wide variety of downtown restaurants, breweries, and wineries.

Amenities:
Our Minnesota marina offers a shower and laundry facility, ship store, lounge, business center, and newly landscaped picnic areas with grills and fireplaces.
