A calm bay with emerald waters dotted by limestone karsts. Explore hidden caves, visit floating villages, and enjoy seafood on boat tours.
Ha Long Bay, a UNESCO World Heritage site in northeast Vietnam, is known for its emerald waters and thousands of towering limestone islands. You can sail through the bay, exploring caves like Sung Sot, or kayak to secluded lagoons. Visit local fishing villages to see how people live and work on the water. The bay's ever-changing scenery creates memorable views, especially during sunrise and sunset.
Limestone Islands and Karsts
You'll find about 1,600 limestone islands and islets scattered across 1,500 square kilometers in Ha Long Bay. These range from small rocky outcrops to larger forested islands with beaches. Many limestone formations rise steeply from the water. Over millions of years, wind and waves have sculpted the limestone, creating caves, arches, and distinctive formations.
Cruising the Bay
An overnight cruise gives you a comprehensive Ha Long Bay experience. Most trips last 2-3 days and stop at various islands and caves. You'll sleep on a traditional-style junk boat, waking to misty views of the karst islands. During the day, kayak to hidden lagoons, swim at quiet beaches, and explore floating villages. The bay's colors are particularly vivid at sunrise and sunset.
Caves and Grottoes
Many of Ha Long's limestone islands have extensive cave systems you can explore. Sung Sot Cave (Surprise Cave) is one of the largest, with three enormous chambers filled with stalactites and stalagmites. In Thien Cung Cave, you'll see intricate rock formations illuminated by colored lights. Dau Go Cave has historical significance as a meeting place for Vietnamese resistance fighters. Remember to bring sturdy shoes and a flashlight for navigating the sometimes slippery cave interiors.
Floating Villages
Several floating fishing villages remain in Ha Long Bay, giving you a glimpse into traditional life on the water. Cua Van, one of the largest, has about 130 households living in colorful floating homes. Take a small boat tour through the village to see daily activities like fishing, pearl farming, and children attending floating schools. While tourism has brought changes, respectful visits can help support the villagers' way of life.
When to Visit
Plan your trip to Ha Long Bay between October and December for comfortable temperatures and clear skies. From January to March, it can be chilly and misty, creating a moody atmosphere but limiting visibility. April to September brings warm weather, with occasional storms from July to September. Expect more visitors during Vietnamese holidays, so check dates in advance. A 2-3 day trip allows you to experience the bay's changing moods.
Getting There
Most people reach Ha Long Bay by a 3-4 hour drive from Hanoi. You can book a shuttle bus through your cruise company or hire a private car for more flexibility. A new highway has reduced travel time. For a different perspective, take a seaplane from Hanoi and fly over the bay before landing. In Ha Long City, cruise boats depart from Tuan Chau Marina or Bai Chay Tourist Wharf.
