Island City Harbor

Island City Harbor is a unique marina located in Sabula, Iowa — the state’s only island city — nestled along the scenic Mississippi River and home to the Jackson County Welcome Center. Formed after the construction of Lock and Dam #13 in 1939, Sabula offers a one-of-a-kind island setting surrounded by river bluffs and beautiful views. The harbor features 140 boat slips for vessels up to 80 feet, along with amenities including a harbor store, gas dock, bathhouses, and laundry facilities. Visitors can rent pontoons, kayaks, and canoes, or enjoy the adjacent beach and lake for family-friendly outdoor fun. For an unforgettable stay, guests can book unique overnight rentals, including a floating cottage and four houseboats.
