Dark & Bright Cave - Lan Ha Bay

Dark and Bright Cave Halong Bay, located near Cat Ba Island in Lan Ha Bay, is one of the most captivating Halong Bay tourist attractions. The cave features two unique caverns: one completely dark, where a torch is needed, and another filled with natural light, which inspired its name. Surrounded by a peaceful lagoon and stunning landscapes, it’s perfect for those on an overnight cruise tour in Halong Bay.

To explore the cave, you can join a local sampan, a traditional bamboo rowing boat, or try Dark and Bright Cave kayaking provided on most boat tours. The 315-meter-long Dark Cave is a magical experience, with its thousands of shimmering stalactites and stalagmites. Inside, the temperature is noticeably warmer, thanks to a small hot spring. Additionally, you can visit the nearby Cua Van Village, one of Halong Bay's five iconic fishing villages.

The Light Cave has a 4m wide arched entrance and is approx. 100m long and leads to a gorgeous sunlit, tranquil lagoon, surrounded on all sides, by enormous, rocky, limestone karst cliffs.

The cliffs are covered in an abundant, natural habitat of green vegetation, orchids, and ‘weeping’ fig trees. The clear waters of the lake support a variety of sea life with shrimp, fish, crab, and cuttlefish
