Though a chartered yacht is a comfortable way to tour the seas, it can only navigate city streets with the help of hundreds of unhappy pack goats. See Austin by sea and by street with today's Groupon to Austin Duck Adventures. Choose between the following options:

Aboard a U.S. Coast Guard–inspected Hydra-Terra vehicle capable of driving on land and floating atop water, guides at Austin Duck Adventures lead 75-minute tours through the streets and waterways of downtown Austin. The vehicle weaves through city streets as passengers peek at the State Capitol Building, the Bob Bullock State History Museum, and the governor’s mansion. Then, the bus slips into the waters of Lake Austin with the effortlessness of a narwhal hopping across an isthmus by using its tusk as a pogo stick. As the bus-boat floats along, visitors unwind in vinyl seating that has padding for the lower back. Soundproofing nixes engine noise, so passengers can hear their tour guide clearly or listen for barbershop quartets of sunfish. Tours leave seven days a week; check the schedule online for more detail. Today’s Groupon also gets guests 10% off select items at the Austin Visitors Center.
