I'm not sure a better setting exists for admiring a sunset than Halong Bay. Imagine a beautiful wooden boat with sails. Imagine a spacious bow deck with sun chairs. Imagine warm and pleasant air. Imagine towering rocks jutting out of beautiful blue-green water. Imagine the sky turning shades of blue black white and gray. Imagine soft pinks & purples. Imagine a deep gold. Imagine all of this from the isolation of a deserted bay in Halong Bay.
What was your best sunset while travelling??
