Formally known as Fort Hertz, Putao, the most northerly town in Myanmar in the foothills of the Eastern Himalayas, was one of the British Empire’s most remote outposts. Today, Putao remains completely cut off from the outside world by millions of acres of subtropical rainforest and jagged peaks. It is famous as a jumping-off point for trekkers who want to explore the region’s deep forests, wildlife sanctuaries, snow-capped mountains and variety of ethnic hilltribe villages.
