A guided tour is one of the best ways to acquaint yourself with a new city, second only to proclaiming yourself its king and observing the types of local produce that get tossed at you. Hit the ground running with this Groupon.

$29 for a Hoover Dam Express Tour ($59.99 Value)

Professional drivers navigate buses from the bright lights of downtown Las Vegas toward the churning waters of the Hoover Dam. The five-hour tour begins as an air-conditioned coach picks up each participant at his or her hotel. They then shuttle passengers toward the manmade wonder, providing narration of the sights as they pass through cities that include Henderson and Boulder City. Once buses arrive at the Hoover Dam, riders receive a full two hours to tour the on-site power plant or throw confetti from the structure’s top and time how long it takes for it to reach the bottom. The return voyage chauffeurs patrons to the Ethel M Chocolates factory and to a lush botanical garden for a stroll. The tour ends as the bus drops tourists off at their hotel and immediately turns back into a pumpkin full of poker chips.
