Wake up in the bay, setting your alarm a little earlier than normal if you want to enjoy an onboard sunrise. Board the tender and explore a local fishing village before coming back to the cruise ship for breakfast. Then take to a bamboo row boat and head to the Dark & Bright Cave, one of Halong Bay’s most atmospheric water caves. Look out for monkeys on the jungled shores, sometimes visible in the gaps between the trees. Head back to the cruise ship before slowly cruising back to Hai Phong. Disembark and head back to Hanoi – you’ll arrive before 4pm on day two. Enjoy a rest before your overnight train to Dong Hoi in the late evening.
