A train journey across this teetering steel bridge is sure to be one of the most memorable experiences of any trip in Myanmar. Connecting Pyin Oo Lwin in Mandalay Region to Hsipaw in northern Shan, the train slows as it approaches the deep gorge with the 119-year-old steel frame soaring above it. As the train slowly clunks across, look out the window to see the huge drop below, the gorge filled with dwarfed trees and rock cliff faces.
