The most popular way to see Halong bay is on a two or three day cruise aboard motorised replica traditional junks. For a large portion of the year the bay is shrouded in mist, despite putting a dampener on the weather it adds a mystical atmosphere. Swimming: is best from May to October, when the weather is hot and the water crystal clear. Swimming is possible at countless sites in Halong Bay, either off the shores of islands or in cave grottos. The peaceful waters of the bay means swimming is rarely dangerous due to strong currents, but care should be taken when swimming near rocky ledges that may be covered with oysters and other shellfish. Kayaking: is a rewarding way of exploring caves and getting close up and personal with the region’s natural wonders. Typically, kayaks are inflatable and your party is taken to a starting point by boat, which stays on standby and provides support when needed. With this arrangement and the calmness of the bay’s waters, kayakers can feel quite safe and fully enjoy their paddling. Wildlife watching: in Halong Bay is very satisfying, with the variety of habitats supporting a wide variety of creatures. There are a few species of primates that inhabit the forests and mangroves, while the wetlands protect numerous species of birds. There is also a great range of reptiles, insects and bats. Helicopter tours: are a fantastic way of seeing the magic of Halong Bay from a different perspective. Helicopter tours operate from airports in Hanoi and Hai Phong, and can be arranged for any time of day. Dawn and dusk flights are particularly spectacular. |
