8:00 AM: After breakfast depart to Ha Long Bay, one of the most spectacular UNESCO World Heritage Areas and the world’s largest marine limestone ‘karsts’ landscape. There you’ll board a traditional-style boat for four-hour cruise on the bay to discover grottoes and caves. In the fine weather, you’ll be able to swim or climb up high for an overview of the Bay’s remarkable seascape. Seafood lunch will be served on the boat.
