Emerald City Trolley's cars may not run on tracks any longer, but their road-ready tires are just about the only thing that differentiates them from the old-fashioned trolley cars of yore. At the helm of this green, yellow, and wood-trimmed beauty is an experienced guide, who pilots it around Seattle with stops at notable city sightseeing destinations. Hop-on/hop-off routes allow passengers to visit The Space Needle, Pike Place Market, Experience Music Project, and off the beaten path to The Ballard Locks, The Woodland Park Zoo, and Kerry Park Overlook.
