What to expect During this tour?

Caves and limestone mountains makes the signature seascape of Halong Bay and Lan Ha Bay. Taking a Halong Bay Cruise without visiting a cave is a huge regret. Thousands of caves and grottos hidden in the mountains, are waiting you to discover. Located in the edge of Lan Ha Bay and Ha Long Bay, Dark and Bright Cave is a nice beauty spot for guests to explore and sightseeing. Here, imposing islands surround a quiet lagoon, sheltered from the sea swells and only accessible via a 100m long sea cave. The grotto looks like a big gate, opening a sanctuary of peace behind. Across the cave, you would discover a quiet and poetic lagoon nestled in the mountains.
