The new Mahanakhon SkyWalk is a thrilling new addition to Bangkok's roster of tourist attractions, says CNN. The SkyWalk is located at the top of Thailand's tallest completed building, King Power Mahanakhon. The 1,030 feet-high observation deck and rooftop bar offers 360-degree views of Bangkok. As soon as visitors enter the elevator on the ground floor they ascend to the 74th floor in 50 seconds.
