King Power Mahanakhon in Bangkok is a high-rise observation deck that looks down on the city's night views. It operates a glass-floor skywalk and observation areas on the 75th and 78th floors. The ride from the 1st floor to the 74th floor takes about 40 seconds, and large backpacks must be left in free lockers. Around sunset, visitors crowd in and seating is scarce on both the rooftop and indoors.
