There are many excursion boats which leave from or stop at the Port of Dubuque. The various boats provide a range of sightseeing options from one hour, one or two days, one week and beyond. Some of the boats start and end their trips at the Port of Dubuque, and some make a brief stop-over during a long cruise. The large excursion boats load and unload passengers from the Port of Dubuque's American Trust River's Edge Plaza, and offer one day or multi-day trips on the Mississippi River. A complete listing of the docking schedule for the large excursion boats can be found below.
These companies leave from the Ice Harbor in the Port of Dubuque and offer 1 to 3 hour long guided boat trips on the Mississippi River. Both boats have daily tours, from May through October. Boat access into and out of the Ice Harbor in Dubuque is dependent on river stage. A river stage of 16.5 feet or higher could result in the closure of the flood wall gates, restricting access to the harbor. A link to the current river stage and each river boat's website can be found below.
