Kajak around the island of Halong bay
Halong Bay is a World Heritage Site with beautiful limestone pillars with caves and grottoes that are hidden just waiting for you to explore them.
There are multiple tours to Halong Bay sold by touristinformations and hotels. You can book both from CatBa island or from Halong City depending on where you’re staying and on how many days you wish to book. But for the ultimate experience you might want to go kajaking on your own.
