Discover Quito on this hop-on hop-off trolley tour, an easy way to explore the UNESCO-listed city enveloped by mountains and volcanoes. Thread your way through Old Town, capture bird's-eye views from a hilltop and listen to live commentary about the city founded on the ruins of an Incan city. Choose from a variety of pass options and see Quito during one, two or three days. Upgrade to a 'plus' pass to visit La Mitad del Mundo — the Middle of the World — and stand tall over the equatorial line, with one foot in each hemisphere.
