Halong Bay, located in the northeastern region of Vietnam, is one of the world’s most breathtaking natural wonders. Its otherworldly landscape of emerald waters, towering limestone islands known as karsts, caves and floating villages leave visitors with an everlasting impression. Halong Bay had long been on my travel bucket-list, and I was able to visit it a few years ago as part of a larger two-week Southeast Asia tour through Gate 1 Travel.
The mystical bay, whose name means “Descending Dragon” is a place of natural beauty and serenity, with its nearly 2,000 islands (of which only 40 are inhabited) covered in lush rainforests. As one explores the bay by boat, every twist and turn offers a unique and spellbinding view.
The distinctive landscape was formed over millions of years through a combination of erosion, tectonic activity, and weathering. Originally part of a massive limestone plateau, the movements of the Earth’s crust caused the area to subside over time, creating valleys and eventually the bay itself. The limestone gradually dissolved by acidic rainwater, leading to the formation of caves, sinkholes, and the iconic towers that rise dramatically from the water. In addition, the rise and fall of sea levels helped to sculpt the bay into its current magnificent form. Its beauty and history have led it to being designated a UNESCO World Heritage Site.
As part of our tour, we spent a day on a traditional wooden boat exploring the vast emerald bay, counting the towering tree topped limestone towers. Our tour also included a walk through Sung Sot Cave, one of the many that inhabit the bay. Here are some of the top sites to see when visiting Halong Bay:
Halong Bay Caves
One of the highlights of visiting Halong Bay is exploring its numerous caves renowned for their stunning formations. In addition, the bay is dotted with numerous smaller grottoes. In total, there are nearly 60 caves and grottos that have been identified. Most of the tour operators allow time for exploring some of the caves. Some offer the ability to explore them by kayak or rowboat offering an intimate perspective of the bay’s diverse ecosystem and its captivating beauty.
Sung Sot Cave (Surprise Cave) – The largest and most popular cave is Sung Sot Cave, known for its impressive stalactites and stalagmites, illuminated by colorful lighting. Discovered by French explorers in 1901, the cave is divided into two main chambers that reach nearly 100 feet, the first resembling a wide theater hall. The second chamber’s ceiling stretches endlessly, covered with unique rock formations that resemble sentinels, animals, and other figures. The cave’s grandeur and natural beauty make it a must-visit spot in Halong Bay. Reaching the cave requires climbing a steep trail to the entrance.
Thien Cung Cave (Heavenly Palace Cave) – Another spectacular cave that should be visited is Thien Cung, located in the southwest section of Halong Bay. Its interior is covered with intricate formations that resemble a palace, hence the name. The cave’s stalactites and stalagmites are illuminated by natural light streaming through the cave’s crevices. One of the legends of the cave is about a dragon king and queen who held their wedding inside the cave, blessing it with its beauty. The entrance to the cave is in the middle of an island, requiring a hike up the hill.
Me Cung Cave (Maze Cave) – While Me Cung Cave, also known as Maze Cave, is less known than others, it’s well worth a visit. The small cave gets its name from the complex network of chambers and passageways, resembling a maze. Besides the ancient stalactites and stalagmites, visitors can find fossilized remains of freshwater creatures, indicating that the cave was once submerged. It also houses vestiges of human activity dating to the Stone Age. Getting to the entrance requires climbing about 80 feet along steps, but once there, you’ll be offered stunning views of the bay.
Dau Go Cave (Wooden Stakes Cave) – Dau Go Cave, one of the oldest in Halong Bay, is steeped in legend. It’s said that in the 13th century, Vietnamese General Tran Hung Dao hid wooden stakes inside the cave to prepare for battle against Mongol invaders. The cave’s chambers are filled with impressive stalactites and stalagmites. The entrance to the cave also offers panoramic views of the bay, making it a popular spot for photographers.
Halong Bay Islands
Cat Ba Island – The largest island in Halong Bay, Cat Ba is a destination in its own right. Archaeological evidence suggests that people have lived on Cat Ba Island for almost 6,000 years. The island is home to Cat Ba National Park, which offers opportunities for hiking, wildlife spotting, and exploring the island’s rugged terrain. The park is home to 32 species of mammals, including the endangered Cat Ba langur, one of the rarest primates in the world. Once numbering nearly 5,000, today there are approximately 80 langurs left in the wild. There are also hundreds of other types of monkeys, such as the macaque, that frolic across the island. Cat Ba Island also features stunning beaches, like Cat Co Beach, where visitors can relax and enjoy the natural beauty of the area. There is a 11-mile hiking trail that leads to a mountain peak, and along the way there are food stalls in the small village of Viet Hai.
Cannon Fort, located on the southern tip of Cat Ba Island, was constructed by Japanese soldiers during World War II. Today’s remnants include tunnels, bunkers, gun placements and trenches, as well as viewing decks overlooking the island. The fort also includes a small museum and café.
Titov Island – Named after the Soviet astronaut Gherman Titov who visited the island in 1962, Titov Island is renowned for its stunning panoramic views of the bay and beautiful white sand beach. Visitors can hike up a steep path to the top of the island, where they are rewarded with breathtaking views of the surrounding karsts and islands. After the hike, relax on the island’s crescent-shaped white sand beach, and clear blue waters ideal for swimming, kayaking and snorkeling.
Bo Hon Island – Bo Hon Island is located at the heart of Halong Bay, characterized by high limestone mountains and vertical cliffs. The island is surrounded by many small islands, and is famous for its grottoes including Sung Sot Cave, Luon Cave, Trinh Nu Cave and Trong Cave (Drum Cave).
Floating Villages
About 1,600 people live within four fishing villages in Halong Bay. These villages of small and colorful floating houses offer a glimpse into a traditional way of life that has endured for generations. These floating villages are home to communities that have adapted to living in harmony with the sea. Their residents rely on fishing for a living, with a lifestyle largely unchanged despite the modern world’s encroachment. The provincial government has a policy to relocate the households living in the bay to resettle, in order to stabilize their life and to protect the landscape of the heritage zone. A limited number will be retained for sightseeing tours. Reaching the islands can be done through organized boat tours or renting private boats (that offer a more personalized experience).
Cua Van Floating Village – Cua Van Floating Village is one of the largest and most well-preserved floating villages in Ha Long Bay. This picturesque traditional fishing village is located about 12 miles from the Tuan Chau tourist pier. The village of about 700 people offers a glimpse into the lives of local fishermen who have lived in the bay for generations. The village is surrounded by stunning limestone formations and consists of floating houses, a school, and a cultural center. Visitors can explore the village by boat or kayak, interacting with the locals and learning about their unique way of life.
Vung Vieng Fishing Village – Vung Vieng Fishing Village is located in smaller Bai Tu Long Bay, which is adjacent to Halong Bay. At one time, Bai Tu Long Bay was crowded with ships and boats from China to exchange goods. Vung Vieng village was a wealthy fishing village with a reputation for culturing pearls. The village is surrounded by majestic towering limestone karsts. Today it consists of about 100 families, and is less visited than other spots, providing a peaceful and authentic experience. Visitors can take a bamboo boat ride through the village or try their hand at traditional fishing methods.
