Ha Long Bay
Picture above, this cluster of 1,600 islands, many untouched by human hands, is perhaps the most famous of Vietnam’s natural heritage sites.
Those islands, many of them looming limestone structures sprinkled with jungle vegetation, are dotted across the Gulf of Tonkin. The most iconic vision you could have of Ha Long Bay is of bobbing wooden boats drifting amid its waterways, with the sunlight streaming down from on high.
