Hotel at a Glance: Grand Harbor Resort and Waterpark

Nestled in the Port of Dubuque, Grand Harbor Resort and Waterpark is surrounded by a historic downtown, scenic bluffs, and the Mississippi River. Enjoy the view from your comfortable room or head downstairs for family-friendly fun at the indoor water park. Select option in this deal includes passes for four, letting you zoom down slides, play in waterspouts, or float down the lazy river.

  • Grab a bite at Tony Roma’s Restaurant, which serves up award-winning barbecue ribs and juicy steaks.

  • Get a workout while looking out at the bluffs from the hotel’s renovated fitness center.
  • Raise the stakes: Bowl or see a comedy show at neighboring Diamond Jo Casino, or head to nearby Q Casino for Vegas-style games.
  • The Mighty Mississippi: The National Mississippi River Museum & Aquarium features wetland nature trails and freshwater aquariums. It’s just a short walk from the hotel.
  • Find a new favorite wine at the nearby Stone Cliff Winery, where you can sample cabernet sauvignon and riesling, as well as strawberry-rhubarb wine.

Dubuque, Iowa: Pastoral Charm Along the Mississippi River

Located along the Mississippi River in eastern Iowa, just across the Wisconsin border, Dubuque’s natural setting makes it ideal for picturesque hikes such as Heritage Trail, a 26-mile mountain trek. The trail links Dubuque with Dyersville, the site where Field of Dreams was filmed. A stroll along the Port of Dubuque’s riverwalk goes past Victorian architecture, eclectic sculptures by local artists, and the city’s iconic clock tower.

For a history-centered day trip, take a scenic 20-mile drive east of the river to the charming town of Galena, Illinois, where you’ll find wineries, antiques stores, and blacksmith shops. The Ulysses S. Grant Home sits on a hill overlooking the town. The 18th president and Union general was given this Italianate house upon his triumphant return to his hometown after the Civil War ended in 1865.
