Iowa's oldest city, Dubuque (population 62,000) has shaken out of its long industrial sleep, remaking its Mississippi River waterfront as a lively destination. The Mississippi Riverwalk moves through the aggressively redeveloped area, part of a 26-mile Heritage Trail stretching to the Field of Dreams movie site in Dyersville.
The route starts at the Smithsonian-affiliated National Mississippi River Museum and Aquarium with fresh-water aquariums and cool hands-on exhibits. In summer, live music rocks the riverside amphitheater. River's Edge Plaza, a 5,000-square-foot outdoor pavilion, serves as a landmark for Mississippi riverboats and excursion vessels.

A numbered lock-and-dam system divides the Mississippi River into ever-deeper pools, allowing the Army Corps of Engineers to control water levels. The 16 gates and 600-foot-long chamber of Dubuque's Lock and Dam No. 11 are powerful to behold, filling or emptying the chamber to deliver tiny fishing boats and giant barges alike along the river's "stairsteps." Free tours are offered at 2 p.m. Sundays Memorial Day through Labor Day (563/582-0881; missriver.org). Eagle Point Park, above Lock and Dam No. 11, provides picnic spots and views of the Mississippi (563/589-4263; cityofdubuque.org).
