Ha Long Bay is a popular destination for many travelers, which means that the main tour routes can be very crowded. If you're looking for a more peaceful experience, consider taking a Lan Ha Bay cruise, which includes 2-way transfers from your hotel in Cat Ba. On this cruise, you'll have the opportunity to kayak through Dark and Bright Cave and Bat Cave, swim on Ba Trai Dao Beach and in a lagoon, visit floating fishing villages, and enjoy lunch on your boat.
