Dark and Light Cave in Ha Long Bay

Once you arrive, a dazzling combination of white limestone karsts, emerald green waters and the dark mystery of the caves create a wonderful atmosphere making this a trip worth taking.
The cave is accessible by kayaks or boats, and offers an exciting exploration experience. Inside, visitors will find two large caves filled with an array of rock formations and stalactites. The upper level of the cave is illuminated by sunlight, while the lower level is in complete darkness – making it the perfect spot for adventurers seeking a thrilling experience. 
Two caves in one
The cave is named Dark & Light Cave because it’s actually a system made up of two separate caves. Dark Cave is 100 meters long with very little natural or artificial light so you will need a flashlight inside! Light Cave, on the other hand, is considerably shorter and has tonnes of natural light beaming through gaps and holes in the rock making it feel like a church carved by Mother Nature herself. Light Cave is always accessible whereas Dark Cave is sometimes swallowed by the tide.
Overall, taking a trip to Dark and Light Cave in Ha Long Bay is an unforgettable experience that is sure to leave visitors with lasting memories. Overall, taking a trip to Dark and Light Cave in Ha Long Bay is an unforgettable experience that is sure to leave visitors with lasting memories.
