HẠ LONG BAY, VIETNAM | "Vịnh Hạ Long — Where the Dragon Descended"
Hạ Long Bay is the most dramatic seascape in Southeast Asia — a UNESCO World Heritage Site of 1,969 limestone karst islands rising from the emerald waters of the Gulf of Tonkin in formations of such geological variety and density that navigating between them by boat feels like moving through a three-dimensional landscape painting. The islands were formed over 500 million years by the carbonate rock platform of the South China Sea being dissolved by rain and seawater into the tower karst formations visible today, their near-vertical cliff faces colonized by tropical vegetation and pierced by sea caves that contain some of the oldest evidence of human habitation in Vietnam. Legend says the islands were created by a family of dragons sent by the Jade Emperor to defend Vietnam from invaders — their descending breath turning to jewels and jade that solidified into the islands that blocked the enemy fleet.
The palette of Hạ Long is the specific green-grey-emerald of tropical karst: the deep emerald of the bay water in clear weather, the grey-green of the limestone cliffs rising vertically from the water, the lush green of the tropical vegetation clinging to every horizontal surface, and the extraordinary pearl-grey of the bay under the morning mist when the islands emerge from the fog like ink-wash painting.
