The Big Bus open-top hop-on, hop-off sightseeing tour in Hong Kong primarily operates three distinct daytime routes alongside periodic or specialized night tours. The first is the Red Route, which takes passengers across major urban areas on Hong Kong Island, including Central, Wan Chai, and Causeway Bay, highlighting notable landmarks and bustling commercial districts. The second is the Green Route, designed to trace Hong Kong Island's southern coastline, servicing locations such as the Peak Tram lower terminus, Repulse Bay, Aberdeen, and the famous Stanley Market. The third is the Blue Route, which focuses on Kowloon by traveling through Tsim Sha Tsui, Temple Street, and various cultural and shopping hubs. These routes allow travelers flexibility in exploring different facets of the territory.
