Though a chartered yacht is a comfortable way to tour a river, it can only navigate city streets with the help of hundreds of unhappy pack goats. Tour Cincinnati in style and comfort with today's Groupon: for $17, you get two tickets for a 45-minute amphibious city tour from Ride The Ducks Newport (a $34 value). The schedule slates tours from noon to 5 p.m., starting on Third Street in front of Newport on the Levee. This Groupon expires November 25.

Plunking guests into amphibious vessels based on a 1940s General Motors military design, the tour guides at Ride The Ducks Newport lead excursions through greater Cincinnati via city streets and the Ohio River. Tours spend about 25 minutes on the water as sightseers paint mental watercolors of local attractions, including Newport Aquarium, the Roebling Suspension Bridge, and the World Peace Bell. Along the way, guides regale tourists with tales about Cincinnati's role in films and songs, as well as stories about the city's history and famous personalities that surprise even lifelong residents. Tourists may bring drinks with lids (no alcohol or liquid nitrogen allowed), and vessels furnish guests with life jackets and Wacky Quackers that make duck noises to complement the tour's duck's-eye views.
