Ha Long Bay is one of the world's most magnificent natural wonders - and experiencing it from the water makes every photograph feel inadequate. More than 1,600 limestone islands rise dramatically from the jade-green Gulf of Tonkin, draped in tropical forest and morning mist. Kayak into Luon Cave, explore the dazzling chambers of Sung Sot, and watch sunrise paint the bay in amber and gold from your cruise deck. Reserve your Ha Long Bay voyage now.
