Denver Trolley Co. is bringing back the old-fashioned trolley ride—with a modern twist. Owner David Pike noticed that despite the city’s inclination for offbeat transportation like pedicabs and horse-and-carriage rides, Denver lacked the historic transit archetype that other cities celebrate: a trolley system. So as of September, in lieu of a party bus, you can rent Dolly, a refurbished red and green trolley car fitted with wooden seats that face each other, for BYOB parties, weddings, or a ride to Red Rocks. “The trolley has a unique feel,” Pike says. “Very nostalgic.”
