We embarked on a 24 hours cruise in the world's 8th wonder, in two junks, under a gray sky that afternoon, but with no rain. Present on all tourist posters of Vietnam, Halong is shown in the picture with a blue azure sky, but the reality is very different! According to our guide and the sailors who travel there all year long on the junks, there are 60 days per year of nice weather only! It is often gray, foggy and sometimes the fog is so dense that boats cannot leave their mooring! Our photos of March 2012.
