The Green Line focuses on one of Oʻahu’s iconic landmarks—Diamond Head. From Waikiki, the trolley transports you to the Diamond Head trailhead (or vicinity), passing through stops like the Honolulu Zoo, KCC Farmers Market (operates on Saturdays), and key community spots in Waikiki and surrounding neighborhoods. It’s a direct, still scenic route designed for those wanting convenient access to nature without detouring too far.
