The spectacular islands of Bai Tu Long Bay, immediately northeast of Halong Bay form Bai Tu Long National Park and are every bit as beautiful as its famous neighbour. In some ways it’s actually more stunning, since it’s only in its initial stages as a destination for travellers with the bay and its islands still unpolluted and relatively undeveloped. As with Halong Bay, the best way to experience the full gamut of limestone pinnacle scattered seascape is by cruise.
Hanoi travel agencies, including Ethnic Travel, run boat trips into the Bai Tu Long area. Charter boats can also be arranged to Bai Tu Long Bay from Halong City's Bai Chay Tourist Wharf; rates start at around 300,000d per hour and the trip there takes about five hours.
