Dark & Light Cave

Dark and Light Cave in Halong Bay is a unique frog-jaw-shaped cave consisting of two small caves, Dark Cave and Light Cave. While Dark Cave is not open for tourists due to its narrow and deep structure, Light Cave, with its 3 meters in height, 4 meters in width and 100 meters in length, is a must-visit attraction for those who want to explore the cave on boat or kayak. The landscape here is stunning, with ancient fossil traces of fresh-water snails found on the cliffs, monkeys, Benjamin fig trees, and orchid flowers blooming fragrant scent. Dubbed as the underwater Sung Sot Cave, Dark and Light Cave is a true hidden gem of Halong Bay that will leave visitors in awe.
